What is a chemical equation ? Explain with the example.
Answers
Answer:
The method of representing a chemical reaction with the help of symbols and formulae of the substances involved in it is known as chemical equation. For example, zinc metal reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas.
Explanation:
symbolic representation of compounds are substances involved during a chemical reaction is called chemical equation.
There are two types of chemical equation :-
1. Balanced chemical equation - an equal number of atoms of different elements in reactant and product are known as balanced chemical equation. for example zinc react with dilute sulphuric acid to give zinc sulphate and hydrogen.
Zn + H2SO4 ---> ZnSO4 + H2
2. unbalanced chemical equation - an equal number of atoms of one or more elements in the reactants and products is known as unbalanced chemical equation. For example hydrogen react with oxygen to form water.
H2 + O2 ---> H2O
