The Lewis structures in which there are no formal charges is the most stable. Hence, structure (b) is the more stable form of FNO2.
<h3>Lewis structure</h3>
The question is incomplete but I will try to answer you as much as I can. Now the equation is missing hence we can't numerically caculate the enthalpy chnage of the reaction from bond energies. However, we can do this using the formula; Σbond energy of reactants - bond energy of products.
Concerning the Lewis structures of FNO2, the most stable structure is structure (b) as shown in the image attached where the atoms have no formal charges.

Answer:
Answer in explanation
Explanation:
A renewable source of energy is an energy source that cannot be depleted. It is an energy source with constant abundance and hence it is always in abundance. What we are saying is that they are energy sources that cannot be used up. Although it might sometimes be that it is unavailable at some instances, this does not take away the fact that it is abundant and cannot be depleted, although the strength at different times may vary. Example of renewable energy sources include solar energy, wind energy, hydroelectric power source etc. These sources are never depleted and are in abundance.
Non renewable source of energy are those sources of energy that can be depleted. A good example of this can be seen in fossil fuels. Fossil fuels are usually burned to produce energy. They are used up in the process and it will require an additional amount of fossil fuel to be restocked for the energy to be continually supplied.
Food labels can tell someone how nutrient-dense a food is. It can show calories, fat, and others. Hope that helps.

<h3>What is the energy?</h3>
We know that the energy of the photon could be obtained by the use of the equation;
E = hf
E = energy
h = Plank's constant
f = frequency
For the first line;
E = 6.6 * 10^-34 Js * 3.45 x 10^14 Hz = 2.3 * 10^-19 J
Given that;
E = hc/λ
λ = hc/E
λ = 6.6 * 10^-34 * 3 * 10^8/2.3 * 10^-19
λ = 8.61 * 10^-7 m or 861 nm
The color is violet
For the second line;
E = 6.6 * 10^-34 Js * 6.53 xx 10^14 Hz
E = 4.3 * 10^-19 J
E = hc/λ
λ = hc/E
λ = 6.6 * 10^-34 * 3 * 10^8/4.3 * 10^-19
λ = 4.60 * 10^- 7 m or 460 nm
The color is blue
