Write the rules of writing chemical equations.
Answers
Answer:
Answer. Rules followed in writing chemical equations are: ... A chemical equation should be written with the reactants (if there are two or more should be separated by '+' symbol, same applicable to products) on the left side of an arrow and the products of the chemical reaction on the right side of the equation.
In a chemical equation the formula or symbols of the reacting substances or reactants are written on the left of the sign of equality (=) and the symbols or formulas of the products are written on the right of it.
The number of atoms of different elements present in the reactants before chemical reaction must be equal to the number of atoms of different elements in the products formed after the reaction. So, to make balance the symbol or formula must be multiplied by the required number.
If the reactants or products are more than one, a plus (+) sign is put between the formula and the symbols.
If the number of molecule is more than one then the number is used before the formula.
An arrow sign () is used to indicate that the reaction moves towards the products from the reactants. Instead of an arrow sign,and equals sign (=) may also be used. However, the equation has to be balanced on both sides.
