Check the statement(s) that is(are) true. Check All That Apply An excited atom can return to its ground state by absorbing electromagnetic radiation. An excited atom can return to its ground state by absorbing electromagnetic radiation. The energy of an atom is increased when electromagnetic radiation is emitted from it. The energy of an atom is increased when electromagnetic radiation is emitted from it. The energy of electromagnetic radiation increases as its frequency increases. The energy of electromagnetic radiation increases as its frequency increases. Niels Bohr quantized electromagnetic radiation. Niels Bohr quantized electromagnetic radiation. Red light is more energetic than blue light. Red light is more energetic than blue light. The frequency and wavelength of electromagnetic radiation are inversely proportional. The frequency and wavelength of electromagnetic radiation are inversely proportional.

The energy of electromagnetic radiation increases as its frequency increases.

The frequency and wavelength of electromagnetic radiation are inversely proportional.

Explanation:

According to Max Plank's equation, the energy of electromagnetic radiation is given by E=hf where h= Plank's constant and f= frequency of the electromagnetic radiation. This means that the energy and frequency of electromagnetic radiation and its energy are related by a direct proportion. As frequency of the electromagnetic radiation increases, the energy of the radiation increases also.

However, frequency and wavelength of electromagnetic radiation are inversely related. The frequency decreases with increasing wavelength of electromagnetic radiation.

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.
