Question

Representation of Chemical reaction​

Answer 1

$\huge\underline{\overline{\mid{\bold{\red{ANSWER-}}\mid}}}$

• Chemical reaction is defined as the process which leads to transformation of chemical substances from one form to another. In a chemical reaction the substances undergoing transformation are called reactant and the new substances that are formed are called products.

• For example :- A + B ―> C + D represents a chemical reaction in which reactants A and B undergo transformation to form products C and D.

The transformation can occur by combination of more than one reactant, decomposition of a reactant and displacement of atoms or molecules in one reactant by atoms or molecules of other reactants.

Answer 2

Answer:-

• A chemical reaction can be represented by writing symbols, formulae of the elements or compounds reacting together. such a representation is called chemical equation.

• A chemical equation should be balanced the number of atoms of same element on reactant side should be equal to the number of atoms on the product side,

Reactant ------------> Product

L.H.S. -------------> R.H.S.

HCI + NaOH ----------> NaCI + H2O

acid + base ----------> salt + water
