titrated with a 0.200 M solution of the base, LiOH. Write the balanced chemical reaction for neutralization reaction: HClO4 (aq) + LiOH (aq) → LiClO4 (aq) + H2O (l) Write the NET ionic equation for the neutralization reaction. OH⁻ (aq) + H⁺ (aq) → H2O (l) Compute the pH of the titration solution. Show your work i) before any of the base is added ii) after 25. mL of base is added iii) after 50. mL of base is added A student performs the titration with the same chemicals but with smaller volumes of each chemical . Which of the following titration curves could represent the titration. Explain A because this entails a strong acid and a strong base. Question 2 A student performs a titration of an unknown acid with a strong base and gets the following titration curve: a) The student consults the list of pKa of acids shown below. If the acid is listed in the table below, which is the most likely identity of the unknown acid? Explain. Acid Ka HF 7.2 x 10-4 CH3COOH 1.8 x 10-5 H2CO3 4.3 x 10-7 HBrO 2.0 x 10-9 The unknown acid is HBrO because the calculated Ka is in between 50^-4 and 50^-6 and 2.0 x 10^-9 lies in between them. b) What is the initial molarity of the acid? 10^-3 = 0.001M Question 3 a) Describe the components and the composition of an effective buffer solution. Explain how the components of the buffer allow the buffer to maintain its pH. An effective buffer solution has a weak acid and its conjugate base or a weak base and its conjugate acid. A buffer solution is most effective when the ratio of its component concentrations is close to 1, also when the pH is equal to the pka of the acid.; The components of the buffer allow the buffer to maintain its pH because buffers can absorb excess H+ions or OH– ions. An employer is interviewing four applicants for a job as a laboratory technician and asks each how to prepare a buffer solution with a pH of 5.0. The following constants may be helpful: hydrazoic acid, pKa = 4.74 Boric acid, pKa = 9.23 Archita A. says she would mix equal molar solutions of hydrazoic (HN3) and sodium azide (NaN3) solutions. Bradley B. says she would mix equimolar Boric acid (H3BO3) and HCl solutions. Carlos C. says he would mix equimolar Boric Acid (H3BO3) and sodium dihydrogen borate (NaH2BO3) solutions. Delia D. says he would mix equimolar hydrazoic Acid (HN3) and NaOH solutions. b) Which of these applicants has given an appropriate procedure? Explain your answer Delia because she is using Sodium hydroxide which results in a pH of 5. NaOH is a strong base and in order to have an effective buffer a weak acid must be incorporated which is the HN3. c) Explain what is wrong with the erroneous procedures. The rest all incorporate a strong acid and a strong base or a weak acid and a weak base which don’ result in an effective buffer. d) The applicants have access to the 1 Liter volumes of each of the solutions listed above. They have access to graduated cylinders. In order to make 1.0 Liter of the correct 5.0 buffer solution, what volumes of the two chemicals must be mixed?

litarianism. To begin with, provide a full description of left-wing authoritarianism. Then identify two traits of totalitarian syndrome and explain why you believe they support the assertion that left-wing authoritarianism is more similar to totalitarianism. There are different understandings as to the nature of representation in an indirect democracy. Name and describe each type. Finally, explain which of these you could expect to find in the parliamentary system and why. What, in the parliamentary context, is confidence? Why is it important, how might it be lost, and what happens if it is lost? The Canadian and the US political systems each contain a Senate. In one of the regimes the Senate is the dominant chamber, in the other it is not. Identify which is which and explain why. Provide a full description of the characteristics of a federal state. In your view, how would Plato and Aristotle classify this type of governmental system?

consulting basis by Loving Organic Foods. In order to get a better idea of what might have motivated customers’ buying habits you are asked to analyze the ages of the customers who have purchased organic foods over the past 3 months. Past research done by the Diligent Consulting Group has shown that different age groups buy certain products for different reasons. Loving Organic Foods has sent a survey to 200 customers who have previously purchased organic foods, and 124 customers have responded. The survey includes age data of past customers who purchased organic foods in the previous quarter. Case Assignment Using Excel, create a frequency distribution (histogram) of the age data that was captured from the survey. You should consider the width of the age categories (e.g., 5 years, 10 years, or other). That is, which age category grouping provides the most useful information? Once you have created this histogram, determine the mean, median, and mode. After you have reviewed the data, write a report to your boss that briefly describes the results that you obtained. Make a recommendation on how this data might be used for marketing purposes. Be sure to conduct adequate research on organic foods industry, organic market analysis, and healthy food industry using IBISWorld database or other databases such as Business Source Complete (EBSCO) and Business Source Complete - Business Searching Interface in our online library.

chases frozen turkeys at a constant wholesale price of $1/turkey, which is its full marginal cost for supplying turkeys. During July, only a small number of wealthy people are interested in buying turkeys in Pilgrim. Their demand curve is P = 10 – .02 Q, where P is Wegboys’ retail price for turkeys during the month and Q is the quantity of turkeys purchased. The demand curve for these wealthy people is constant – it is the same curve in both November and July. During November, a large number of less wealthy people enter the market to purchase turkeys for Thanksgiving. Their demand curve for Wegboys’ turkeys is P = 4 – .0005Q. In other months of the year, they do not purchase turkeys at any price. a. (5 points) What price should Wegboys charge in July to maximize its profits? Calculate its profits from turkey sales. b. (5 points) Demonstrate that Wegboys can earn a higher profit if it lowers its retail price for turkeys during November (you can do this without finding the optimal price). Explain the basic economic intuition.

tarting the process of meiosis. Draw the chromosomes, depicting them inside the cell, as you would expect them to appear during Metaphase I. (Note: there is more than one correct answer for this prompt. You only need to draw one of the answers.) 2.How many copies of gene A are present in this parent cell during Metaphase I? 3.How many total chromosomes would you have after DNA replication (synthesis)? 4.While examining a specific tissue in this organism, Bridget noticed some cells with more than one nucleus (this is commonly found in many species, including humans!). What could have happened during the process of cell division to yield these multinucleate cells? 5.In one of her harebrained experiments, Dr. Milam remembers treating some cells from one of her organisms with a drug that resulted in the cell being unable to replace RNA primers with DNA. Which protein in the cells was most likely affected by this drug treatment? 6.In another one of her experiments, Dr. Milam treated cells with a different drug that caused an adenosine in gene A to be paired with a cytosine instead of a thymine during DNA replication. However, Dr. Milam remembers that the amino acid sequence of the protein product of gene A wasn’t actually changed. How could you explain this observation?

To What Extent Are Genetic Variations a Life or Death Situation? -In other words, how do variations in a species’ DNA promise them Life or Death? What are the possible causes of genetic variation in a population? To what extent does genetic variation depend on mutations? How Has Our Increased Understanding of Genetics Affected Society? How has our increased understanding of genetics affected the world? How has our increased understanding of genetics affected the United States?

there was no Age and/or Sex entered) has been created. It is called Newmarket_Cleaned.csv. Data file: Newmarket_Cleaned.csv (Links to an external site.) . Direct HTTP link: https://unh.box.com/shared/static/p8x4xlbean3rlslmfskfu74fe89yjui8.csv Please use it for this problem. Consider the “Model 4” developed in class, which contained Age, Age^2, and Sex as independent variables. First re-create this model with the cleaned dataset (you will need to create the Age^2 column; you can verify your model summary against the one from class), and then proceed with this problem. Make the necessary changes to the model to incorporate Year as a categorical explanatory variable (you may need to change how R interprets the variable, before running this model). Does the year of the race seem to be related to mean finishing time, after taking into account the other variables in Model 4? Use the 0.05 significance level. Explain your work/logic, and key output to support your answer. Using the updated model, after accounting for age and sex, what is the expected difference in finishing times for runners from 2008 versus runners from 2004? Using the updated model, after accounting for age and sex, what is the expected difference in finishing times for runners from 2014 versus 2011? In the above, the directions are to treat Year as a categorical variable. Explain how the regression model would be different if it instead were treated as a numeric variable. What are the assumptions being made about the effect of Year in the two different approaches?

adolescents. I have completed the Literature review. I have to plan a research design for the thesis. ABOUT THE THESIS: Population- 13+ to 19 years adolescents No of IV s- 2 that is, Gender is the First IV and Locus of Control ( LOC) is the second IV Levels of IV- Gender has 2 levels ( male and female). LOC has two levels ( Internal Locus of Control and External Locus of Control). Both IV s are categorical variables. List of DV s- 1. Self Esteem 2. Coping 3. Happiness 4. Academic motivation 5. Exam Anxiety 6. Life Style Each DV will be measured by using appropriate Statistical scales. All DVs will be taken as continuous variables. All the scales measure the quantitative aspect only. DV MEASUREMENT: Each of the scales that will be used to measure DV contains several areas or dimensions or sub-categories. For example, the self-esteem scale contains 78 items divided into 6 categories like personal, social, emotional, academic, intellectual and moral. THESIS AIM- To check the impact of IV s on each of these DV s in isolation and also investigate the interaction effects between gender and locus of external. I will be using the SPSS package for calculations. PROBLEM: Problem 1: Which is the most appropriate Statistical test or design that should be used here? I believe a 2x2 ANOVA will be best suited here. Problem 2: If I am measuring the impact of IV s on each DV in isolation, should I use several Two Way AONVA tables or a single MANCOVA table? Problem 3: Each of the DV is measured using scales containing several dimensions. Are such dimensions of the scales need to be treated as the levels of the dependent variables? In other words, do the levels of DV are decided as per the dimensions of the scale that was used to measure the DV? If this is so, then even if I am measuring the DV s in isolation; each DV will have multiple levels, which in turn will change my design from Two Way ANOVA to perhaps MANCOVA? What is the right approach here? Note: I have not intentionally divided DV into any levels. Kindly help me to arrive at a statistically significant research design! If possible, kindly briefly explain the type of the design as well as the rational or suitability of the sign for my research problem.

y line.Specially from "Since he belonged, even at the age..... Yes, of course, if it's fine tomorrow," said Mrs. Ramsay. "But you'll have to be up with the lark," she added. To her son these words conveyed an extraordinary joy, as if it were settled, the expedition were bound to take place, and the wonder to which he had looked forward, for years and years it seemed, was, after a night's darkness and a day's sail, within touch. Since he belonged, even at the age of six, to that great clan which cannot keep this feeling separate from that, but must let future prospects, with their joys and sorrows, cloud what is actually at hand, since to such people even in earliest childhood any turn in the wheel of sensation has the power to crystallise and transfix the moment upon which its gloom or radiance rests, James Ramsay, sitting on the floor cutting out pictures from the illustrated catalogue of the Army and Navy stores, endowed the picture of a refrigerator, as his mother spoke, with heavenly bliss. It was fringed with joy. The wheelbarrow, the lawnmower, the sound of poplar trees, leaves whitening before rain, rooks cawing, brooms knocking, dresses rustling--all these were so coloured and distinguished in his mind that he had already his private code, his secret language, though he appeared the image of stark and uncompromising severity, with his high forehead and his fierce blue eyes, impeccably candid and pure, frowning slightly at the sight of human frailty, so that his mother, watching him guide his scissors neatly round the refrigerator, imagined him all red and ermine on the Bench or directing a stern and momentous enterprise in some crisis of public affairs.

he efficacy of this spending is therefore relatively important. When it comes to contagious diseases, there are generally two strategies that can be adopted. The first involves prevention, which includes vaccinations to lower or eliminate the risk of contracting a disease. The second involves treatment of those unfortunate enough to get sick, treatment typically requires some form of a drug. Since pharmaceutical companies can produce both vaccines and drugs, we would like to understand the incentives they have to develop each type of medicine. To explore this question, consider a population of 100 consumers, 90 of whom have a low disease risk, say 10%. The remaining ten have a high risk – to make things simple, assume they are certain to contract the disease. In addition, suppose the disease generates personal harm equal to the loss of $100 for each individual when they are infected. Suppose also that pharmaceuticals of either form (vaccines or drugs) are costless to produce (once R & D has occurred) and are perfectly effective Question 2. What price would a profit maximising monopolist charge for a vaccine? What are the monopoly profits on the vaccine? What is the efficient outcome (i.e. SMB = SMC)? What is the welfare under the monopoly and at the efficient allocation? Question 3.Now consider the demand for the drug (assume that the vaccine is not available). Construct the demand function for the drug and plot it on a diagram. What price would a profit maximising monopolist charge for the drug? What are the monopoly profits from the drug? What is the efficient outcome? What is the welfare under the monopoly and at the efficient allocation? Question 4. If the R&D costs of the vaccine and drug are the same, what will the pharmaceutical company do? Explain your answer in terms of the variation in the willingness to pay and the size of the R& D costs. What would a social planner do? Question 5. What are the R&D cost for the vaccine and the R&D cost for the vaccine drug that would make a pharmaceutical company indifferent between developing the vaccine and the drug? Is the social planner indifferent in this case? Explain any difference.
