8. The kinetic energy between the particle is maximum in which state

Particles has the highest kinetic energy when they are in the gaseous state. Kinetic energy is related to heat (also called thermal energy

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
