Answer:
Explanation:
Hello!
In this case, since the heat of fusion of a solid substance stands for the energy required to melt it, which is a phase transition from solid to liquid, we can see that the heat lost by water is that gained by the solid, so we can write:
Thus, by using the water data and its specific heat (4.184), we obtain:
Next, since the heat of fusion of a substance is usually represented in terms of energy per amount of substance, we use the mass of solid to obtain:

Answer:
Structure of the product has been shown below
Explanation:
- N atom in aniline acts as a nucleophile and carbonyl group of propanoic acid acts as an electrophilic center.
- A nucleophilic acyl substitution reaction occurs on mixing and heating mixture of aniline and propanoic acid.
- In this reaction an amide is formed.
- Reaction mechanism goes through addition-ellimination pathway at carbonyl center.
- Full reaction mechanism has been shown below.
