The zinc in a copper-plated penny will dissolve in hydrochloric acid if the copper coating is filed down in several spots (so that the hydrochloric acid can get to the zinc). The reaction between the acid and the zinc is: 2H+(aq)+Zn(s)→H2(g)+Zn2+(aq). When the zinc in a certain penny dissolves, the total volume of gas collected over water at 25 ∘C was 0.957 L at a total pressure of 750 mmHg .
What mass of hydrogen gas was collected?
Consider the reaction
2 NO(g) + 5 H2(g)
→ 2 NH3(g) + 2 H20(g)
The reaction mixture initially contains 6 moles of NO and 10 moles of H2 contained in a 20.0-
liter gas cylinder with a movable piston. At the end of the reaction, the volume has decreased
to 15.7 L. Without doing any calculations, which method is the best for determining the
concentration of NO in the mixture after the reactants have reacted as completely as
possible?
Use stoichiometry: 10 moles of H2 consumes 6 moles of NO, so the final concentration of NO = 0 M
Use the dilution formula: (6 mol NO)(20.0 L) = (x mol NO)(15.7 L)
Use the dilution formula: (2 mol NO)(20.0 L) = (x mol NO)(15.7 L)
Use stoichiometry: 10 moles of H2 consumes 4 moles of NO, so the final concentration of NO = (6
moles - 4 moles NO)/(15.7 L)
The zinc within a copper-plated penny will dissolve in hydrochloricacid if the copper coating is filed down in several spots (so that thehydrochloric acid can get to the zinc). The reaction between theacid and the zinc is 2 H+(aq) + Zn(s) ¡ H2(g) + Zn2+(aq).When the zinc in a certain penny dissolves, the total volume of gascollected over water at 25°C is 0.951 L at a total pressure of748 mmHg. What mass of hydrogen gas is collected?

- Item 4 4 of 16 I Review I Constants I Periodic Table Gases are different from solids and liquids. In a sample of gas, the molecules are far apart. The gas molecules also move around and collide with each other as well as with the walls of the container. These collisions generate pressure. The pressure of a gas can be measured in different units. One convenient unit of measure is called the atmosphere (atm) because it is based on atmospheric pressure. At sea level, the average pressure is 1 atm. As you get higher in altitude, the pressure steadily drops until you leave the atmosphere, where the pressure is very close to 0 atm. Part C The table below shows the different commonly used units of measuring gas pressure. Use this table in the pressure unit conversions. High-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purify chemical substances.

An experiment is performed to measure the mass percent of CaCO3(s) in eggshells. Five different samples of CaCO3(s) of known mass react with an excess of 2.0M HCl(aq) in identical sealed, rigid reaction vessels. The pressure of the gas produced is measured with a pressure gauge attached to the reaction vessel. Since the reaction is exothermic, the reaction system is cooled to its original temperature before Cooling the HCl(aq) to a lower temperature than it was in the original experiment the pressure is recorded.
