Question

"A chemical reaction is nothing but a rearrangement of atoms " Justify the statement

Answer 1

$\huge\mathbb{Answer:}$

• First of all, what is a chemical reaction ?

Such processes which involve a chemical change are said to be chemical reactions. These do involve the formation of new substances with entirely new properties.

• Chemical reactions basically involve the breaking of chemical bonds between the atoms of reacting substances and further making new bonds between the atoms which are rearranged to make new chemical substances.

• For clearance, atoms of different substances or elements do not change to those of other elements, and only rearrangement of atoms take place during the process of chemical reactions.

• Since, only the rearrangements of atoms take place during a chemical reaction, we can define a chemical reaction as the rearrangement of atoms.
