Ammonia is produced from the reaction of nitrogen and hydrogen according to the following balanced equation:
N2 (g) + 3H2 (g) = 2NH3 (g)
1. What is the maximum mass of ammonia that can be produced from a mixture of 176.7 g of N2 and 42.97 g of H2?
2. Which element would be left partially un-reacted?
3. What mass of the starting material would remain un-reacted?
