A candy bar has a total mass of 75.0 grams. In a calorimetry experiment, a 1.25-g sample of this candy bar was burned in a calorimeter surrounded by 1000 g of water. The temperature of the water in contact with the burning candy bar was measured and found to increase from an initial temperature of 21.2°C to a final temperature of 24.3°C. a. Calculate the amount of heat in calories released when the 1.25-g sample burned. (show the work you did)
NH2 CI CI A В Aniline Imine Aminal Stan and Kyle have observed a reaction between the aniline derivative A and acetone. Kenny is of the opinion that the aminal C is the likely product, and decides to replicate the experiment in a more controlled setting. By reacting 2.53 g of aniline (M.M. 157.60 g/mol) with 0.94 g (M.M. = 58.08 g/mol) of acetone, he was able to completely convert both starting materials to the same pure product that Stan and Kyle obtained. %3D Eric is ecstatic. “See, see", he shouts, "your reaction proves me and Stan right! It is an imine!" How does this experiment prove Eric right? ZI ZI

The specific heat of substance C is 0.93 J/(g K) and that of substance D is 1.8 J/(g K). You are given an unknown that could be pure substance C, pure substance D, or a homogeneous mixture of C and D. In the lab you determine that it requires 23.3 J of heat energy to raise the temperature of a 25.0 g sample of the unknown by 1.0 K. What conclusions can you make about the identity of your unknown, from this data?
