The total volume of hydrogen gas needed to fill the Hindenburg was 2.11  108 L at 1.00 atm and 24.7°C. How much energy was evolved when it burned? A) 8.64  106 kJ B) 2.98  1010 kJ C) 3.02  104 kJ D) 2.47  109 kJ E) 4.94  109 kJ

If 22.5 liters of oxygen reacted with excess of hydrogen, how many liters of water vapor could be produced?

Nitric acid can be formed in two steps from the atmospheric gases nitrogen and oxygen, plus hydrogen prepared by reforming natural gas. in the first step, nitrogen and hydrogen react to form ammonia: (g) (g) (g) in the second step, ammonia and oxygen react to form nitric acid and water: (g) (g) (g) (g) calculate the net change in enthalpy for the formation of one mole of nitric acid from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .

We are hoping to create 5.72 grams of glucose. the plant was given 4.75 liters of co2 and 2.81 g of h20. which reactant was the limiting reagent? how much excess mass did we have of the other reactant?
