The great French chemist Antoine Lavoisier discovered the Law of Conservation of Mass in part by doing a famous experiment in 1775. In this experiment Lavoisier found that mercury(11) oxide, when heated, decomposed into liquid mercury and an invisible and previously unknown substance: oxygen gas. 1. Write a balanced chemical equation, Including physical state symbols, for the decomposition of solid mercury(11) oxide (HgO) into liquid mercury and gaseous 0-0 0 09 dioxygen. 2. Suppose 76.0 ml. of lowygen gas are produced by this reaction, at a temperature of 60.0 "C and pressure of exactly 1 atm. Calculate the mass of mercury(II) guide that must have reacted. Round your answer to 3 significant digits.
