Question

Chemical reactions can be represented using symbols and chemical formulae.

• A. True
• B. False

Answer 1

The correct option is A True

• Chemical reactions can be represented using symbols and chemical formulae of the substances involved in the reactions.
• Chemical reaction - A process in which one or more substances react to form one or more new substances.
• The substance that combines or react are known as the reactant.
• The substances that are formed in a reaction are known as products.
• Example - When hydrogen reacts with oxygen it forms a water molecule that has completely different properties that reactants.

$\underset{\mathrm{Reactants}}{\underset{\mathrm{Hydrogen}}{2{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}}\to \underset{\underset{\mathrm{Product}}{\mathrm{Water}}}{2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}$

Thus, the given statement is true.
