A reinforced steel cylinder is filled with 21.0 moles of hydrogen and 12.0 moles of oxygen. The mixture is detonated inside the cylinder causing the following reaction to take place. 2 H2(g) + O2(g) → 2 H2O (g)   What is the theoretical yield, in grams, of the reaction?

What mass of CO2 is produced from the combustion of 1 gal of gasoline? The chemical formula of gasoline can be approximated as C8H18. Assume that there are 2801g of gasoline per gallon.

Barium hydride reacts with water to produce barium hydroxide and hydrogen gas. BaH₂ (s) + 2 H₂O(1)→ Ba(OH)2 (aq) + H₂(g) If 6.389 g BaH2 is combined with 64.000 g H₂O, the reaction proceeds until all the BaH₂ is consumed. The hydrogen gas escapes to the environment, and the final weight of the flask is 70.204 g. The remaining water is evaporated, leaving 7.856 g Ba(OH)2.
