Hydrogen + oxygen yields water
Label what type of reaction (synthesis, decomposition, single replacement, double replacement or combustion)
Write the balanced chemical equation
How much water could you get if you started with 250.0 grams of hydrogen?
How much water could you get if you started with 250.0 grams of oxygen?
Which is the limiting reactant?
Type of reaction: Synthesis
Balanced chemical equation:
2H2 + O2 -> 2H2O
From 250.0 grams of hydrogen, you could get:
250.0 g H2 x (1 mol H2/2.02 g H2) x (2 mol H2O/2 mol H2) x (18.02 g H2O/1 mol H2O) = 5569 g H2O or 5.569 kg H2O
From 250.0 grams of oxygen, you could get:
250.0 g O2 x (1 mol O2/32.00 g O2) x (2 mol H2O/1 mol O2) x (18.02 g H2O/1 mol H2O) = 2814 g H2O or 2.814 kg H2O
The limiting reactant is hydrogen because it produces less water than oxygen.
