Problem 5

The chemical name for limestone, a compound of calcium, carbon, and oxygen, is calcium carbonate. When heated, limestone decomposes into solid calcium oxide and gaseous carbon dioxide. From the names of the products, tell where you might find the atoms of each element after the reaction. How does Dalton's atomic theory explain this?

Problem 8

When 10.0 g of chlorine reacts with mercury under varying conditions, the reaction consumes either $28.3 \mathrm{g}$ or $56.6 \mathrm{g}$ of mercury. No other combinations occur. Explain these observations in terms of the Law of Multiple Proportions.
