Nitrogen gas is reacted with hydrogen gas to form nitrogen trihydride. How many liters of nitrogen trihydride are produced at STP if 80.28 grams of hydrogen gas are reacted in an
excess of nitrogen?
N2 (g) + 3H2(g) ——> 2NH3 (g)

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being
