State the equation which explain how to find the energy of a photon.

To find the energy of a photon you want to use this equation: E=hf

Explanation: E is the energy of the photon in Joules; h is Planck's constant, which is always 6.63*10^-34 Joule seconds; and f is the frequency of the light in hertz.

to find the energy of a photon you need to use this equation e=hf

answer

the ions in solute supperate from eachouthere

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).
