eason for each effect. i) A capacitor creates an electric field which is then observed in another frame of reference. The field is perpendicular to the direction of motion. ii) A capacitor creates an electric field which is then observed in another frame of reference. The field is parallel to the direction of motion. iii) A long wire creates a magnetic field which is then observed in another frame of reference moving along the wire. Comment on what types of forces would be experienced by a charged particle (e.g. an electron) that is stationary in the frames of the capacitor and wire. Discuss why fields parallel to the direction of motion do not show any effect. Include appropriate diagrams and/or sketches.

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?

Body Paragraph 2: Describe what life is really like under these totalitarian governments. Body Paragraph 3: Explain what you think accounted for the rise of totalitarian states after World War I, including how the leaders of these states gained and kept their power.
