In two or more complete sentences explain how to balance the chemical equation and classify its reaction type.
__p4+_02— p203

P₄ + 3O₂ - > 2P₂O₃.

This is an oxidation reaction or an addition reaction or a redox reaction.

Explanation:

Red Phosphorous reacts with limited oxygen in low temperature to form phosphorous trioxide which readily dimerises to form tetraphosphorous hexaoxide. This molecule is actually an anhydride of phosphorous acid, but it's not obtained from the acid itself by dehydration.

This is a type of oxidation reaction, as well as a redox reaction where oxygen is reduced and phosphorous is oxidized. It's also an addition reaction where two reactants produce a single product.

Its balanced by adding 3 before oxygen and 2 before phosphorous trioxide.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
