Answer:
A chemical equation is the use of symbols to represent all the events that took place during a chemical reaction.
1) Reactant's symbols are written on LHS, followed by an arrow. A sign of addition (+) is written between formulae of two reactants. Product's symbols are written on RHS of arrow.
2) State of matter of reactants and products is shown by s ( for solid ), l ( for liquid) and g ( for gas) in brackets, after the formula.
Special conditions, if any is written above or below arrow.
3) Number of atoms of each element should be same on both sides of the arrow.
