Answer:
Compound A is succinic anhydride and B is methyl succinate (the monomethyl ester).
Structural Diagram is attached.
Explanation:
A.
Succinic anhydride appears as colorless needles or white crystalline solid. ... Succinic anhydride, also called dihydro-2, 5-furandione, is an organic compound with the molecular formula C4H4O3. It is the acid anhydride of succinic acid.
B.
Monomethyl succinate is a dicarboxylic acid monoester that is succinic acid in which one of the carboxy groups has been converted to its methyl ester. It is a dicarboxylic acid monoester and a hemisuccinate. ... They have the general structure RC(=O)OR', where R=fatty aliphatic tail or organyl group and R'=methyl group.

<h3>
Answer:</h3>
7.502 kilo calories
<h3>
Explanation:</h3>
<u>We are given;</u>
- Quantity of heat, Q as 31.39 kJ
We are required to convert it to kilo calories
First, we convert it to Joules
1 kJ = 1000 J
Therefore;
31.39 kJ will be equivalent to 31390 Joules
Second we convert Joules to calories using a suitable conversion factor
The suitable conversion factor is 4.184 J/Cal
Thus;
31390 Joules will be equivalent to;
= 31390 J ÷ 4.184 J/Cal
= 7502.39 Cal
Third, we convert calories to kilo calories
1 kCal = 1000 cal
Therefore;
7502. 39 Cal will be equivalent to;
= 7502.39 ÷ 1000
= 7.50239
=7.502 kilo calories
Hence, 31.39 kJ will correspond to 7.502 kilo calories
