Question

If you start the reaction with 2 moles of HCl and 1 mole of NaOH, how many moles of H2O will you produce?

Answer 1

Solution:

The chemical equation:

HCl + NaOH = NaCl + H₂O

According to the reaction equation: when one mole of NaOH reacts with one mole of HCl, one mole of NaCl and one mole of H₂O are formed.

Then,

NaOH - limiting reactant

HCl - in excess.

Therefore,

Since NaOH is a limiting reactant, 1 mole of H₂O will be produced.

Answer: 1 mole of H₂O will be produced.
