To identify the limiting and excess reactants in a reaction. You are given the following reaction:
N2O + 2 H2O --> NH4NO3
Which reactant is limiting if 25 g of N2O and 20 g of H2O are mixed?
The molar mass of N = 14.0 g/mole, H = 1.0 g/mole, and O = 16.0 g/mole

A5 mole sample of liquid acetone is converted to a gas at 75.0°c. if 628 j are required to raise the temperature of the liquid to the boiling point, 15.600 kj are required to evaporate the liquid, and 712 j are required to raise the final temperature to 75.0°c, what is the total energy required for the conversion?
