Question

A shorthand way of representing a chemical change is to use a ___ equation.

Answer 1

Any chemical change in the matter which involves transformation into one or more substances with entirely different properties is known as a chemical reaction.

• Chemical reactions can be represented by chemical equations.
• The substances that take part in the chemical reaction are called reactants and the chemicals which are formed as a result of reacting between reactants is known as product.
• Example: $\underset{\mathrm{Hydrogen}}{2{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Water}}{2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}$
