The equation representing the formation of water from oxygen and hydrogen is: 2H2 + O2 > 2H2O
In this reaction 32 grams of oxygen react with 4 grams of hydrogen to form two molecules of water. The Law of Conservation of Matter (mass) is supported by this reaction because?
A) 2 hydrogen atoms react with 2 oxygen atoms to form 2 water molecules
B) the volume of the oxygen and hydrogen will equal the volume of the water
C) 32 grams of oxygen and 4 grams of hydrogen will produce 36 grams of water
D) the size of the hydrogen and oxygen atoms and the water molecules will be equal

Nitric oxide (no) can be formed from nitrogen, hydrogen and oxygen in two steps. in the first step, nitrogen and hydrogen react to form ammonia: n2(g) + 2 h_2(g) rightarrow 2 nh_3 (g) delta h = -92. kj in the second step, ammonia and oxygen react to form nitric oxide and water: 4 nh_3(g) + 5 o_2(g) rightarrow 4no(g) + 6 h_2o(g) delta h = -905. kj calculate the net change in enthalpy for the formation of one mole of nitric oxide from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
