A student studied the clock reaction described in this experiment using Reaction Mixture 3 : • 10.0 mL 0.010 M KI, • 10.0 mL 0.0010 M Na, S2 Os, 20.0 mL 0.040 M KBrO3, • 10.0 mL 0.10 M HCI, • 0.00 mL H20, according to the procedure given. It took about 45 seconds for the color to turn blue. 1. The number of moles of each reactant does not change when that reactant is mixed with the others, but its concentration does. For any reactant A, Moles of A = MA stock x Vatock = MA mirture x Vmixture The volume of the mixture was 50.0 mL. Revising the above equation gives Vstock (mL) MA mixture = MA stock X 50.0 mL Find the concentrations of each reactant in the reaction mixture, using the equation above: [I] = M [Bro3 ] = M [H+] = 2. What was the relative rate of the reaction? 1000 Relative rate = Time taken (s) Relative rate = 1/sec

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 they found that mercury(II) oxide, when heated, decompose into liquid mercury and an invisible and previously unknown substance: oxygen gas. A. Write a balanced chemical equation, including physical state symbols, for the decomposition of solid mercury (II) oxide (HgO) into liquid mercury and gaseous dioxygen. B. Suppose 72 mL of dioxygen gas are produced by this reaction, at a temperature of 120°C and pressure of exactly 1 atm. Calculate the mass of mercury (II) oxide that must have reacted in grams.
