Answer :

Steps of writing a chemical equation are: -


i. At first, reactants are written followed by a single arrow and then products are written.


ii. If reactants or products are more than one in number then they are separated by a + sign.


iii. The Mass conservation law is followed while writing a chemical reaction. According to which in both the sides of the arrow there must be an equal number of atoms of each type.


iv. Mass of reactants and mass of products must be equal.


v. While balancing a chemical equation first of all atoms other than oxygen and hydrogen are balanced.


vi. After balancing the chemical; equation the physical state of each substance is represented by writing - s, l, g in brackets after each substance indicating solid, liquid and gaseous state respectively.


vii. Substances in solution are represented by writing aq in the bracket after each substance.


viii. Reaction conditions for a reaction to occur like temperature, pressure, catalyst etc. are written above the arrow.


ix. In case of an exothermic and endothermic reaction, amount of energy is written with (+) and (-) sign respectively along with products in R.H.S of the equation.


x. Delta (∆) symbol is sometimes used to represent chemical changes in a reaction.
