Question

Here is a precise problem for the student to solve:Balance the chemical equation for the reaction between sodium hydroxide (NaOH) and hydrochloric acid (HCl) to form sodium chloride (NaCl) and water (H2O).

Answer 1

atoms of each element is equal on both sides of the equation.Here is the unbalanced equation:NaOH + HCl  NaCl + H2ONow, let's balance the equation:1. There is one Na atom on both sides of the equation, so it is already balanced.2. There is one O atom on both sides of the equation, so it is also balanced.3. There are two H atoms on the left side  one from NaOH and one from HCl  and two H atoms on the right side  two from H2O , so the H atoms are balanced.4. There is one Cl atom on both sides of the equation, so it is balanced as well.Since all the elements are balanced, the balanced chemical equation is:NaOH + HCl  NaCl + H2O
