chemical equations should be balanced?
Schanical fouatiodn is said to be bolanu​

Answer 1

Answer:

A balanced equation is in which the elements of the sum of reactants have the same number of molecules as the elements in the reactants.

A balanced equation is necessary due to the law of conservation of mass, which states that mass is neither created nor destroyed during a chemical reaction. That is why the number of molecules of each element should be same on the LHS and well as the RHS for the mass to be same.

Answer 2

Answer:

•A chemical equation gives information about the reactants and products through their symbols and formulae.

•Its gives the ratio of molecules of reatants and products.

•It gives the relative masses of reatants and products .

•We can calculate the volumes of gases liberated at given condition of temperature and pressure using molar mass and molar volume relationship.

•Using molar mass and Avagadro's number we can calculate the number of molecules and atoms if different substances.

•All the chemical reations follow law of conservation of nass that is total mass of reactants must be equal to the total mass of products.
