How many moles of water can be made from 4 moles of oxygen gas and 16 moles of hydrogen gas? What is the Limiting Reagent?

Answer 1

1. Write the equation and balance it.
2H2 + O2 ==> 2H2O

2a. Using the coefficients in the balanced equation, convert moles oxygen to moles H2O.
2b. Same procedure convert moles hydrogen to moles H2O.
2c. It is likely that these answers will be different; it should be obvious that one of them MUST be wrong. The correct value is ALWAYS the smaller one and the reactant producing the smaller value is the limiting reagent.
