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. CaCO3s→CaOs+CO2g 2. Suppose 48.0L of carbon dioxide gas are produced by this reaction, at a temperature of 260.0°C and pressure of exactly 1atm. Calculate the mass of calcium carbonate that must have reacted. Round your answer to 3 significant digits.
