Question
____________ is used to represent the chemical reaction by using a formula.
- Chemical change
- Chemical reaction
- Chemical Equation
- Both b and c
Hint:
Chemical equations are symbolic representations of chemical reactions.
The correct answer is: Chemical Equation
Chemical equations are symbolic representations of chemical reactions in which the reactants and the products are expressed in terms of their respective chemical formulae. They also make use of symbols to represent factors such as the direction of the reaction and the physical states of the reacting entities.
