Question

give reason why the following balanced chemical equations are considered to be incorrect H2 +o gives h2o , ca+o gives cao​

Answer 1

Answer:

Because the Oxygen cannot exist alone in nature.

Explanation:

The following given balanced chemical reaction are not actually balanced even the number of elements are same on both sides.

Reason:-

The gases such as hydrogen, oxygen, chlorine exist as diatomic molecules and cannot exist be alone in nature.

But in given balanced reaction their is only one oxygen atom which is not exist because molecules of oxygen is exist as diatomic molecules.

Hence, writing the balanced chemical equation in this ways is wrong.
