Balance the following reaction: NaOH + HCI -&gt;NaCI +H2O​
Fiesta28 [93]

The chemical reaction is balanced.

Explanation:

We have the following chemical reaction:

NaOH + HCl → NaCl + H₂O

It is a neutralization reaction between a base and an acid which produce a salt and water.

To balance the chemical reaction the number and type of atoms entering the reaction have to be equal to the number and type of atoms leaving the reaction. We do that to conserve the mass.

We do not need to add other stoechiometric coefficients because the reaction is already balanced.

1 Na atom is entering the reaction and 1 Na atom is leaving the reaction

1 Cl atom is entering the reaction and 1 Cl is leaving the reaction

1 O atom is entering the reaction and 1 O atom is leaving the reaction

2 H atoms are entering the reaction and 2 H atoms are leaving the reaction
