n the following balanced neutralization reaction equation, how many moles of HCl are required to completely neutralize 0.040 moles of NaOH?
HCl + NaOH → NaCl + H2O
moles acid=mole base
To determine the number of moles of HCl required to completely neutralize 0.040 moles of NaOH, we can use the balanced equation. The balanced equation shows the stoichiometric ratio between the reactants and the products.
From the balanced equation:
HCl + NaOH → NaCl + H2O
We can see that one mole of HCl reacts with one mole of NaOH, which means the stoichiometric ratio between them is 1:1. This implies that for every mole of NaOH, we need an equal amount of HCl.
Therefore, if we have 0.040 moles of NaOH, we would also need 0.040 moles of HCl to completely neutralize it.
