Write the balanced equation for the following chemical reactions. Hydrogen $+$ Chlorine $\to$ Hydrogen chloride

Balanced chemical equation: A balanced chemical equation is the representation of a chemical reaction in which the number of atoms of each element is the same on both the reactant and product sides. Word equation to symbolic equation: - In the given reaction, Hydrogen reacts with Chlorine to form Hydrogen chloride - The chemical reaction can be represented as: $\underset{\text{ Hydrogen }}{{\mathrm{H}}_2(\mathrm{g})}+\underset{\text{ Chlorine }}{{\mathrm{Cl}}_2(\mathrm{g})}\to \underset{\text{ Hydrogen chloride }}{\mathrm{HCl}(\mathrm{g})}$ Balancing the Chemical Equation: Step 1: Write the number of atoms of each element Element Reactant side Product Side $\begin{array}{lll}\mathrm{H}& 2& 1\\ \mathrm{Cl}& 2& 1\end{array}$ - From the table, it is clear that the atoms of hydrogen and chlorine are not balanced. Step 2: Balancing the unbalanced atoms - In order to balance the equation, we will make the coefficient of $\mathrm{HCl}$ as 2 . - Now the equation becomes Element Reactant side Product Side $\begin{array}{lll}\mathrm{H}& 2& 2\\ \mathrm{Cl}& 2& 2\end{array}$ Hence, the balanced chemical equation is ${\mathrm{H}}_2(\mathrm{g})+{\mathrm{Cl}}_2(\mathrm{g})\to 2\mathrm{HCl}(\mathrm{g})$ Hydrogen Chlorine Hydrogen chloride
