9) An experiment was done in which zinc was reacted with hydrochloric acid in a vessel to make hydrogen gas and zinc chloride. After heating off everything in the dish except the remaining solid zinc chloride, this data was considered: Mass of empty evaporating dish: 113.5 g Mass of evaporating dish + zinc (before the reaction): 116.0 g Mass of evaporating dish + zinc chloride (at end of exp't): 118.8 g Given the following lab data, what is the empirical formula of zinc chloride? A) ZnCI B) Zn4CI C) Zn2Cl D) ZnCl2 E) Zn2Cl4

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(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 mercury and gaseous dioxygen. 2HgO + heat 2Hg (1) + O2(g) 2. Suppose 40.0 mL of dioxygen gas are produced by this reaction, at a temperature of 110.0 °C and pressure of exactly 1 atm. Calculate the mass of mercury(II) oxide that must have reacted. Be sure your answer has the correct number of significant digits. X x10 A 18 Ar 8.

Soda ash (sodium carbonate) is widely used in the manufacture of glass. Prior to the environmental movement much of it was produced by the following reaction. CaCO3 + 2 NaCl → Na2CO3 + CaCl2 Unfortunately, the byproduct calcium chloride is of little use and was dumped into rivers, creating a pollution problem. As a result of the environmental movement, all of these plants closed. Assume that 125g of calcium carbonate (100.09 g/mol) and 125 g of sodium chloride (58.44 g/mol) are allowed to react. Determine how many grams of useful sodium carbonate (105.99 g/mol) will be produced. How many grams of useless calcium chloride (110.98 g/mol) will be produced? You should also determine how many grams of excess reactants are left (indicate which one is the limiting reactant)
