What happens during a neutralization reaction?

If 34.2 grams of lithium react with excess water, how many liters of hydrogen gas can be produced at 299 kelvin and 1.21 atmospheres? 2 li (s) + 2 h2o (l) yields 2 lioh (aq) + h2 (g)

Astudent reacts 13 moles of iron with 21 moles of oxygen according to the following equation:
