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. 2. suppose 88.0l of carbon dioxide gas are produced by this reaction, at a temperature of 380.0°c and pressure of exactly 1atm. calculate the mass of calcium carbonate that must have reacted. round your answer to 3 significant digits. g
