I got a problem set of 58 questions, and I had trouble with this two. Can you help me?
If 10.0 g of carbon is combined with an exact, stoichiometric amount of oxygen (26.6 g) to produce carbon dioxide, what mass, in grams, of CO2 can be obtained? That is, what is the theoretical yield of CO2? [Molar masses: C: 12.011 O2: 32.00 CO2: 44.01]
Burning coal and oil in a power plant produces pollutants such as sulfur dioxide, SO2. The sulfur-containing compound can be removed from other waste gases, however, by the following reaction:
2 SO2(g) + 2 CaCO3(s) + O2(g) 2 CaSO4(s) + 2 CO2(g)
[Molar masses: 64.07 100.1 32.00 136.2 44.01]
(a) Name the compounds involved in the reaction.
(b) What mass of CaCO3 is required to remove 155 g of SO2?
(c) What mass of CaSO4 is formed when 155 g SO2 is consumed completely?
