46. True or false. Chemical reactions do not involve changes in the chemical bonds that join
Naddika [18.5K]

Answer:

Chemical reactions do not involve changes in the chemical bonds that join

atoms in compounds :

<u>False</u>

Explanation:

Chemical reaction are the reaction in which old bonds break and new  bonds are formed . The formation of new bond result in formation of new compounds . This happen because new bond are result of linking different atoms by the bond.

For example : Water formation from Oxygen and Hydrogen is a chemical process :

2H_{2}+O_{2}\rightarrow 2H_{2}O

Original(old) bonds are :

H-H bond in H2 and O-O bonds in O2

In H2 = Hydrogen is joined to Hydrogen

IN O2 = Oxygen is joined to oxygen

New Bonds =

O-H bonds in water (H2O)

Oxygen is joined to hydrogen = New Bond formation

Hence,

<u>Chemical reactions do involve changes in the chemical bonds that join </u>

<u>atoms in compounds</u>
