The sun sending out electromagnetic waves is best describes the source of radiation heat.
Radiation heat is the form of electromagnetic waves.
Radiation heat, commonly referred to as thermal radiation, is the electromagnetic radiation that defines how photons exchange heat. The technique of heat transfer known as radiant heat does not require a medium to be propagated in.
Two molecules colliding with each other produce kinetic energy, moving objects have kinetic energy. Radiation heat is thermal energy. Sun directly sends thermal radiation through electromagnetic waves.
Hence , The sun sends out electromagnetic waves directly is best describes the source of radiation heat.

Answer:
I interpret the answers as being nonmetallic and metallic.
Explanation:
Nonmetals are in groups 14 - 18. Electronegativity is referred to as the want to attract electrons to an atom. Noble gases (group 18) have eight valence electrons in their outer subshells and are therefore atomically stable. Elements with only 7 valence electrons are very electronegative because they desire to obtain an electron to reach stability more than a group 2 element would (they are more likely to drop electrons by giving away in order to reach atomic stability of a group 18 element). This coincides with electron configuration, which is a very lengthy topic to cover. You can conduct more research if you would need it.
2SO2(g)+O2(g)→2 SO3(g), here reaction entropy decreases as the number of gas moles decreases from reactions to products.
HCL(g)+NH3(g)→NH4CL(s), entropy decreases as molecules of gas are converted into solid.
CO2(s)→CO2(g), entropy increases as gas is formed from a solid.
Cao(s)+CO2(g)→Caco3(s), entropy increases as gas is converted into a solid.
B.
As you can see both NO and NH3 have 4 moles therefore it is 4:4 between the molecules or in other words a 1:1 ratio in simplest forms
