Chemistry
what volume of ammonia gas will be produced when 8.01 L of hydrogen react completely in the following equation. N2 + 3H2 > 2NH3 this stuff is so confusing because one little word seems to change the entire process for solving.

Chemistry
what volume of ammonia gas will be produced when 1.26L of nitrogen react completely in the following equation? N2 + 3H2 > 2NH3 Please if someone can just give me the order of operation it will be much appreciated because chemistry is just not my forte.

Chemistry
What mass of oxygen is consumed when 1.73L of carbon dioxide (STP) are produced in the following equation. C4H8 + 6 O2 > 4 CO2 + 4 H2O please help and show your work. My answer for this problem is 11.12g/O2. I have no confidence in my answer.

Chemistry
