The space shuttle environmental control system handles excess CO2 (which the astronauts breathe out; it is 4.0% by mass of exhaled air) by reacting it with lithium hydroxide (LiOH) pellets to form lithium carbonate (Li2CO3) and water. If there are seven astronauts on board the shuttle, and each exhales 20. L of air per minute, how long could clean air be generated if there were 25,000 g of LiOH pellets available for each shuttle mission? Assume the density of air is 0.0010 g/mL.
Answer to relevant QuestionsThe element rhenium (Re) has two naturally occurring isotopes, 185Re and 187Re, with an average atomic mass of 186.207 amu. Rhenium is 62.60% 187Re, and the atomic mass of 187Re is 186.956 amu. Calculate the mass of 185Re. Consider the following reaction: 4NH3( g) + 5O2( g) → 4NO( g) + 6H2O(g) If a container were to have 10 molecules of O2 and 10 molecules of NH3 initially, how many total molecules (reactants plus products) would be present ...The production capacity for acrylonitrile (C3H3N) in the United States exceeds 2 million pounds per year. Acrylo-nitrile, the building block for polyacrylonitrile fibers and a variety of plastics, is produced from gaseous ...Many cereals are made with high moisture content so that the cereal can be formed into various shapes before it is dried. A cereal product containing 58% H2O by mass is produced at the rate of 1000 kg/h. How much water must ...In using a mass spectrometer, a chemist sees a peak at a mass of 30.0106. Of the choices 12C2 1H6, 12C1H2 16O, and 14N16O, which is responsible for this peak? Pertinent masses are 1H, 1.007825; 16O, 15.994915; and 14N, ...
