A) to generate the spectrum above a source capable of producing electromagnetic radiation with an energy of 7 * 10 ^ 4 * k * j per mole of photons was used. such radiaton is from which region of the electromagnetic spectrum. justify your answer with a calculation

These radiations is from X-rays region of the electromagnetic spectrum.

Explanation:

Energy of the 1 photon =

Energy of the photon :

(1 kJ=1000 J)

These radiations is from X-rays region(0.1 nm to 10 nm) of the electromagnetic spectrum.

am i too late?

explanation:

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary
