A sample of sandstone consists of only silica (SiO2) and calcite (CaCO3). When sandstone is heated, calcium carbonate decomposes to calcium oxide and carbon dioxide. Silica does not decompose.
A 18.7 mg sample of the sandstone rock yields 3.95 mg of carbon
dioxide.
i) What is the mass of calcium carbonate in the sandstone rock in
milligrams?
ii) What is the percent of calcium carbonate in the sandstone rock?
iii) What is the percentage of silica in sandstone rock?

When limestone (solid CaCO3) is heated, it decomposes into lime (solid CaO) and carbon dioxide gas. This is an extremely useful industrial process of great antiquity, because powdered lime mixed with water is the basis for mortar and concrete — the lime absorbs CO2 from the air and turns back into hard, durable limestone. Suppose some calcium carbonate is sealed into a limekiln of volume 750.L and heated to 770.0°C When the amount of CaCO3 has stopped changing, it is...
