INTRODUCTORY CHEMISTRY-W/MOD.MASTERING.
- 109 An ore sample with a mass of 670 kg contains 27.7% magnesium carbonate, MgCO3. If all of the magnesium carbonate in this ore sample is decomposed to form carbon dioxide, describe how to determine what volume of CO2 is evolved during the process. What would have to be measured to predict the needed volume in advance?arrow_forwardAmmonium chloride, NH4Cl, is a while solid. When heated to 325C, it gives a vapor that is a mixture of ammonia and hydrogen chloride. NH4Cl(s)NH3(g)+HCl(g) Suppose someone contends that the vapor consists of NH4Cl molecules rather than a mixture of NH3 and HCl. Could you decide between these alternative views on the basis of gas-density measurements? Explain.arrow_forwardA self-contained underwater breathing apparatus (SCUBA) uses canisters containing potassium superoxide. The superoxide consumes the CO2 exhaled by a person and replaces it with oxygen. 4 KO2(s) + 2 CO2(g) 2 K2CO3(s) + 3 O2(g) What mass of KO2, in grams, is required to react with 8.90 L of CO2 at 22.0 C and 767 mm Hg?arrow_forward
- One way to state Boyle’s law is All other things being equal, the pressure of a gas is inversely proportional to its volume. (a) What is the meaning of the term inversely proportional? (b) What are the other things that must be equal?arrow_forwardSilane, SiH4, is the silicon analogue of methane, CH4. It is prepared industrially according to the following equations: Si(s)+3HC1(g)HSiCl3(l)+H2(g)4HSiCl3(l)SiH4(g)+3SiCl4(l) a. If 156 mL HSiCl3 (d = 1.34 g/mL) is isolated when 15.0 L HC1 at 10.0 atm and 35C is used, what is the percent yield of HSiCl3? b. When 156 mL HSiCl3 is heated, what volume of SiH4 at 10.0 atm and 35C will be obtained if the percent yield of the reaction is 93.1%?arrow_forwardPotassium peroxide is used to absorb the CO2 produced by the people in a space vehicle. 2K2O2(s)+2CO2(g)2K2CO3(s)+O2(g)If a person at rest exhales 3.0 L of air per minute and CO2 is 3.4% (by volume) of exhaled air, how many grams of K2O2 are needed per person for a five-day trip. Assume a temperature of 250 and 728 mm Hg pressure.arrow_forward
- What is the value of FT for a sample of gas whose volume is 2.97 L and pressure is 0.0553 atm? What could the volume of the gas be if the pressure were increased to 1.00 atm?arrow_forwardWhat is the value of the ideal gas constant R if the volume is specified in milliliters rather than liters?arrow_forwardConsider these four gas samples, all at the same temperature. The larger boxes have twice the volume of the smaller boxes. Rank the gas samples with respect to: (a) pressure, (b) density, (c) average kinetic energy, and (d) average molecular speed. (Green spheres are He; violet spheres are Ne.)arrow_forward
- Plot the data given in Table 5.3 for oxygen at 0C to obtain an accurate molar mass for O2. To do this, calculate a value of the molar mass at each of the given pressures from the ideal gas law (we will call this the apparent molar mass at this pressure). On a graph show the apparent molar mass versus the pressure and extrapolate to find the molar mass at zero pressure. Because the ideal gas law is most accurate at low pressures, this extrapolation will give an accurate value for the molar mass. What is the accurate molar mass?arrow_forwardExplain why the plot of PV for CO2 differs from that of an ideal gas.arrow_forwardDensities of gases are usually measured in grams per liter g/L. Calculate the density of air if the mass of 15.7 L is 18.6 g.arrow_forward
