Answer:
Conversion of alcohols to alkenes: R-CH2-CHOH-R → R-CH=CH-R + H2O
Conversion of carboxylic acids to acid anhydrides 2 RCO2H → (RCO)2O + H2O
Explanation:
Dehydration
In chemistry, a dehydration reaction is one that involves the loss of water. In organic synthesis, where an acid is often used as a catalyst, there are numerous examples of dehydration reactions: Conversion of alcohols to ethers: 2 R-OH → R-O-R + H2O Conversion of alcohols to alkenes: R-CH2-CHOH-R → R-CH=CH-R + H2O Conversion of carboxylic acids to acid anhydrides 2 RCO2H → (RCO)2O + H2O Conversion of amides to nitriles: RCONH2 → R-CN + H2O

Answer:
Fortified
Explanation:
A fortified food is a food to which nutrients have been included into that ordinarily do not contain such nutrients. The inclusion of the additional nutrient is to provide improved nutrition as well as to meet dietary needs. Food drink such as milk products usually contain added vitamin D, which serves as a fortification. Produced fruit juices can sometimes be found fortified with vitamin D.
Answer:
convenience sampling can be very useful, and as the name suggests convenient. This can also lead to some problems though. If the group chosen is a group for a reason related to your research that could affect your findings. Given the example of students in a psych class, if your research is on physical activity levels in the student population, that could be totally fine to use as your sample because physical activity and psychology courses are not directly related. Conversely, if you were going to do research on intended major of first year college students, choosing just one course to pick from may skew your results (an overestimation of those interested in psych as a major)
