Transcribed Image Text:Ancient Romans built often out of bricks and mortar. A key ingredient in their mortar was quicklime (calcium oxide), which they produced by roasting limestone
(calcium carbonate).
1. Write a balanced chemical equation, including physical state symbols, for the
decomposition of solid calcium carbonate (CaCO3) into solid calcium oxide and
gaseous carbon dioxide.
0
2. Suppose 82.0 L of carbon dioxide gas are produced by this reaction, at a
temperature of 210.0 "C and pressure of exactly 1 atm. Calculate the mass of
calcium carbonate that must have reacted. Round your answer to 3 significant digits.

In each case, she fills a reaction vessel with some mixture of the reactants and products at a constant temperature of 111.0 °C and constant total pressure. Then, she measures the reaction enthalpy AH and reaction entropy AS of the first reaction, and the reaction enthalpy AH and reaction free energy AG of the second reaction. The results of her measurements are shown in the table. C(s) + 2C₁₂(g) → CC₁₁ (g) Complete the table. That is, calculate AG for the first reaction and AS for the second.
