Discussion/Conclusion Questions: [T6]
Based on the chemical formula of the hydrate, calculate the percentage composition (percent by mass) of the hydrated cobalt (II) chloride. Remember to determine the percentage of each element (Co, Cl, H, and O). [T2]
A possible source of systematic error in this experiment is insufficient heating. Suppose that the hydrate was not completely converted to the anhydrous form. Describe how this would affect: the calculated percent by mass of water and the experimental molecular formula (i.e. would x be higher, lower or the same).
Suppose a student spilled some of the hydrated cobalt (II) chloride. Describe how this would affect the calculated percent by mass of water (would it be higher, lower or the same) and the experimental chemical formula of the hydrate. [T2]

Needless to say, this sales strategy will be effective when the distribution channels for the product in question are well planned, when there is sufficient advertising to let the consumers know about the promotion, when the package clearly indicates the coupon redemption scheme with the expiration date, if any, and the packaging of the product is of the right size (neither too big nor too small to serve the needs of the consumer). Of course, all these factors will not help, unless there is an established frequent need for the product for consumers.
Develop a theoretical framework for the above mentioned scenario.

Ques. 14
Read the following information identify the concepts and develop a conceptual model for the scenario below.
Incidence of smoking in movies has started to increase again, after having declined for several decades. According to the National Cancer Institute smoking is seen in at least three out of four contemporary box office hits. What's more, identifiable cigarette brands appeared in about one-third of all movies in 2019. Exposure to smoking in movies is an important predictor of adolescent smoking initiation: smoking in movies has been shown to affect adolescents' intentions to start smoking. In turn, the intentions to start smoking are determined by a more positive attitude toward smoking after seeing a film character smoke. Recent research has revealed that the relationship between seeing a film character smoke and the attitude toward smoking is stronger when a person's identification with a film character increases. These findings are consistent with social learning theory, which predicts that attitudes and behaviors are modeled by observing the behaviors of others.

1)Dorothy Dunning , Chief Production Manager , was on top of the world just two years ago . In her nontraditional job , she was cited to be the real backbone of the company , and her performance was in no small measure responsible for the mergers the institution was contemplating with other well - known global corporations . Of late though , the products of the company had to be recalled several times owing to safety concerns . Quality glitches and production delays also plagued the company . To project a good image to consumers , Dunning developed a very reassuring web site and made sweeping changes in the manufacturing processes to enhance the quality of the product , minimize defects , and enhance the efficiency of the workers , A year after all these changes , the company continues to recall defective products !
