Answer:
Step-by-step explanation:
In terms of the size, we can infer from the discussion that the succinic acid will now have a lower size after it has given off the gas. The lower size implies a decrease in the number of atoms that would be contained in the acid. The gas given off has a particular number of atoms it will carry off during its emission.
We can conclude that succinic acid will have more atoms and a larger size compared to the white solid that results from the heating process.
