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 Lavolisier found that mercury(1I) oxide, when heated, decomposed into liquid mercury and an invisible and previously unknown substance: oxygen gas. 1. Write a balanced chemucal equation, including physical stote symboli, for the decompostion of solid mercury(i1) exide $(\mathrm{HgO})$ into tiquid mercury and gasedus dionvgen. 2. suppose $59.0\mathrm{mL}$ of dioxyen gas are produced by this reaction, ot a temeerature of 150.0 "C and pressure of exacty 1 atm. Calculate the mass of mercury(ii) axide that must have reacted. Be sure your answer has the correct number of significant diges:
