Interpretation Introduction

Interpretation: The balanced chemical equation for the given reaction needs to be determined.

  $\text{Al + HCl }\stackrel{}{\to }{\text{ AlCl}}_{\text{3}}{\text{ + H}}_{\text{2}}$

Concept Introduction: A chemical reaction is a symbolic representation of the conversion of substances to new substances. In a chemical reaction, the substance which involves in conversion is said to be reactant whereas the newly formed substance is called as product. Both reactants and products must be separated by an arrow.

The physical states of reactant and product molecules must be mentioned in parenthesis. Here (aq) indicates the aqueous state of ions and (g) represents the gaseous state of the molecule. To balance a chemical reaction, all the atoms at both sides of the reaction must be the same in number. To balance a chemical reaction coefficient can be added with molecules.
