How to write a Chemical Equation?
Representation of a chemical reaction in terms of symbols and chemical formulae of the reactants and products is known as a chemical equation.
Zn(s) + dil. H2SO4(aq) → ZnSO4(aq) + H2(↑)
(Reactants) (Products)
- For solids, the symbol is "(s)".
- For liquids, it is "(l)".
- For gases, it is "(g)".
- For aqueous solutions, it is "(aq)".
- For gas produced in the reaction, it is represented by "(↑)".
- For precipitate formed in the reaction, it is represented by "(↓)".
