Part A. Multiple Choice Identify the choice that best completes the statement or answers the question. L·atm R = 0.08206 mol · K 1. At 0.982 atm, the height of mercury in a barometer is 0.746 m. If the mercury were replaced with ethanol, what height of ethanol (in meters) would be supported at this pressure? The densities of Hg and ethanol are 13.5 g/cm³ and 0.789 g/cm³, respectively. а. 0.0436 m b. 0.946 m с. 0.760 m d. 12.8 m е. 13.0 m

4. One way to reduce air pollution is to remove potential pollutant gases from an exhaust stream before they are released into the air. Carbon dioxide can be removed from a stream of gas by reacting it with calcium oxide to form calcium carbonate. If we react 5.50 L of CO2 at STP with excess CaO, what mass of calcium carbonate will form?
