science homework-help!

Right, so basically i have 3 questions and they are:

1)Nitrogen reacts with hydrogen to make ammonia
N2+3H2–>2NH3
calculate the maximum theoretical yield of ammonia that can be made by reacting 90g of hydrogen with an excess of nitrogen.

2)In the reaction, only 153g of ammonia was produced. Calculate the percentage yield.

3)Give 3 reasons why the amount of ammonia made is less than theorectical yield.

All help appreciated!
