Question #1 Compare how entropy changes for the following two systems:

System A: Two gases mix when the valve separating two containers is opened.

System B: A solid powder decomposes to form a solid product and a gas product.

Question #2

A 3.81-gram sample of NaHCO3 was completely decomposed in an experiment.

2NaHCO3 → Na2CO3 + H2CO3

In this experiment, carbon dioxide and water vapors combine to form H2CO3. After decomposition, the Na2CO3 had a mass of 2.86 grams.

Determine the mass of the H2CO3 produced.

Calculate the percentage yield of H2CO3 for the reaction. Show your work or describe the calculation process in detail.
