The great French chemist Antoine Lavoisier discovered the Law of Conservation of Mass in part by doing a famous experiment in 1775. In this experimen Lavoisier found that mercury(II)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(II)oxide (HgO) into liquid mereury and gaseous dioxygen 8 X 2 2 2. Suppose 27.0 ml of dioxygen gas are produced by this reaction, at a temperature of 130.0 C and pressure of exactly 1 atm. Calculate the mass of mercury(It) oxide that must have reacted. Round your answer to 3 significant digite: Cla
