Hydrozine (N2H4) emits a large quantity of energy when it reacts with oxygen, which has
led to its use as a fuel for rockets:
N2H4(l) + O2(g) → N2(g) + 2 H2O(g).
How many grams of water are produced

Which is the layer underground where all empty spaces are filled with a combination of air and water ?

Asample of ammonia reacts with oxygen as shown. 4nh3(g) + 5o2(g) 4no(g) + 6h2o(g) what is the limiting reactant if 4.0 g of nh3 react with 8.0 g of oxygen? o2 because it produces only 0.20 mol of no. nh3 because it produces only 0.20 mol of no. o2 because it produces two times less no than nh3. nh3 because it produces three times more no than o2.
