Answer:
electromagnetic waves
Explanation:
Radiation is the transfer of heat energy through space. Most of them are sent through electromagnetic waves.
Air is the most simplest mixture of gas and gas. It contains oxygen, CO2, nitrogen, etc.
The products being more stable than the reactants is the factor which would reduce the yield of a reaction and is denoted as option B under standard conditions.
<h3>What is a Chemical reaction?</h3>
This is the process in which one or more substances which are referred to as reactants are converted into new substances which we call the products.
A chemical reaction involves atoms exhibiting different bond formation so as to ensure they acquire an octet configuration and promotes proper stability of the products.
When the products are more stable than the reactants it means it is unable to form other products thereby decreasing the yield which is why it was chosen as the most appropriate choice.

#SPJ1
P: Good conductor of heat and electricity - R: the delocalized electrons are
free to move around the structure
P: High melting and boiling points - R: the bonds in metals are very strong
P: Ductile (can be stretched and squashed) - R: because the electrons are free to move, the atoms can slide over each other.
P: Malleable (can be hammered into shape) - R: the bonds in metal don't break easily
