Question

Before balancing a chemical reaction, check the formulae of all symbols and products are correct.

• A. True
• B. False

Answer 1

The correct option is A True

• An equation in which the number of each atom of an element on the reactants side is equal to the number of each atom of an element on the product side is called a balanced equation
• A balanced chemical equation tells the amounts of reactants and products needed to satisfy the Law of Conservation of Mass
• This means there are the same numbers of each type of atom on the left side of the equation as there are on the right side of the equation.
• So it is very important that before balancing a chemical reaction, check the formulae of all symbols and products are correct.
• For example, the balanced equation will be:

$2{\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to 2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$

So, the given statement is true.
