formed from one or more substances is called Chemical Reaction.
Examples -
- Rusting of Iron
- Burning of wood
- Formation of Curd
- Respiration etc.
Following observations help to determine whether a chemical
reaction has taken place:
1) Change in state
2) Change in colour
3) Evolution of a gas
4) Change in temperature
Reactant: The substances which take part in chemical reaction.
Product: The substances which are formed in a chemical reaction.
Chemical Equation:
- Symbolic representation of a chemical reaction is said to be
Chemical equation.
- It involves uses of symbol of elements or chemical formula of
