Balance the following equation: NH3(g) + O2(g)———> N2(g) + H2O(g)

2SO2 + O2 → 2SO3 Specifically, if 12.6 g of sulfur dioxide is combined with 3.90 g of molecular oxygen, what mass (in g) of SO2, O2, and SO3 will be present after the reaction is allowed to go to completion?

If 36.0 g of C3H8 and 112 g of O2 are placed in a closed container and the mixture is ignited, what is the maximum mass of CO2 that could be produced? The other product of the reaction is water.     68.9 g     74.7 g     86.8 g     92.4 g     108 g
