The easiest way to find out is to look at the electromagnetic spectrum. Visible light is in the middle. Infrared rays, microwaves, and radio frequency all have longer wavelengths than visible light. I hope this helps :-)
The statement that is true among the given statements is ΔH1 = 2ΔH2. The correct option is d. ΔH1 = 2ΔH2
From the question,
We are to determine which of the given statements is true.
From the given reactions,
We have
1. N2 (g) + O2 (g) ----> 2NO (g) ΔH1
and
2. 1/2 N2 (g) + 1/2 O2 (g) ---> NO (g) ΔH2
ΔH1 is the enthalpy change for reaction 1
and
ΔH2 is the enthalpy change for reaction 2
Enthalpy is an extensive property. The enthalpy change for a given reaction depends on the stoichiometry of the reaction.
From the given equations,
We can observe that the stoichiometry of reaction 1 is twice that of reaction 2.
Therefore, the enthalpy of reaction 1 will also be twice the enthalpy of reaction 2
That is,
ΔH1 = 2ΔH2
Hence, the statement that is true among the given statements is ΔH1 = 2ΔH2. The correct option is d. ΔH1 = 2ΔH2

Explanation :
According to the molecular orbital theory, the general molecular orbital configuration will be,
As there are 7 electrons present in nitrogen and 9 electrons in fluorine.
(a) The number of electrons present in molecule = 7 + 9 = 16
The molecular orbital configuration of molecule will be,
The formula of bonding order =
The bonding order of =
(b) The number of electrons present in molecule = 7 + 9 - 1 = 15
The molecular orbital configuration of molecule will be,
The bonding order of =
(c) The number of electrons present in molecule = 7 + 9 + 1 = 17
The molecular orbital configuration of molecule will be,
The bonding order of =
Answer:the reaction in which two water molecules produce ions is called self-ionization of water
For example
H2O➡️H+ +OH-
