Sometimes in lab we collect the gas formed by a chemical reaction over water (see sketch at nght). This makes it easy to isolate and measure the amount of gas produced. Suppose the O, gas evolved by a certain chemical reaction taking place at 30.0 Cs collected over water, using an apparatus something like that in the sketch, and the final volume of gas in the collection tube is measured to be 89.6 mL. Sketch of a gas-collection acparae Calculate the mass of O, that is in the collection tube. Round your answer to 2 significant digits. You can make any normal and reasonabie arpeon about the reaction conditions and the nature of the gases.

50 The first step in processing zinc metal from its ore, ZnS, is to react it with O2 according to the reaction 2ZnS(s)+3O2(g)2ZnO(s)+2SO2(g) If 620 kg of ZnS is to be reacted, what volume of oxygen at 0.977 atm 34.0 C is needed (at a minimum) to carry out this reaction?
A mixture of chromium and zinc weighing 0.362 g was reacted with an excess of hydrochloric acid. After all the metals in the mixture reacted, 225 mL dry of hydrogen gas was collected at 27C and 750. torr. Determine the mass percent of Zn in the metal sample. [Zinc reacts with hydrochloric acid to produce zinc chloride and hydrogen gas; chromium reacts with hydrochloric acid to produce chromium(III) chloride and hydrogen gas.]

61 As one step in its purification, nickel metal reacts with carbon monoxide to form a compound called nickel tetracarbonyl, Ni(CO)4, which is a gas at temperature above about 316 K. A 2.000-L flask is filled with CO gas to a pressure of 748 torr at 350.0 K, and then 5.00 g of Ni is added. If the reaction describe occurs and goes to completion at constant temperature, what will the final pressure in the falsk be?
A 19.9-mL volume of a hydrochloric acid solution reacts completely with a solid sample of magnesium carbonate, producing 183 mL of CO2 that is collected over water at 24.0C and 738 torr total pressure. The reaction is 2HCl(aq)+MgCO3(s)CO2(g)+H2O(l)+MgCl2(aq) What is the molarity of the HCl solution?
Before small batteries were available, carbide lamps were used for bicycle lights. Acetylene gas. C2H2, and solid calcium hydroxide were formed by the reaction of calcium carbide, CaC2. with water. The ignition of the acetylene gas provided the light. Currently, the same lamps are used by some cavers, and calcium carbide is used to produce acetylene for carbide cannons. (a) Outline the steps necessary to answer the following question: What volume of C2H2 at 1.005 atm and 12.2 C is formed by the reaction of 15.48 g of CaC2 with water? (b) Answer the question.
