प्रश्न
‘Dilute hydrochloric acid is added to sodium hydroxide’. Give a word equation and a molecular equation of the same. Is the equation written, a balanced equation. Give reasons.
उत्तर
Word equation:
\[\ce{Sodium hydroxide + hydrochloric acid -> sodium chloride + water}\]
Molecular equation:
\[\ce{NaOH + HCl -> NaCl + H2O}\]
No. of atoms of each element of reactant/s = No. of atoms of each element of product/s.
Therefore, the above equation is said to be a balanced equation.
