The product of a reaction between these two elements is
.
Explanation:
The oxidation state of an ion in a compound is equal to its charge.
The aluminum having a charge of +3 because oxidation state is +3
The oxide is having charge of -2
The product of these reactants will produce a chemical compound.
The compound formed is
i.e Aluminium oxide. The compound while getting formed will share the charge and cation A+ will have the charge of anion and anion will have the charge of cation. This will result in a compound as there should be a neutral charge on the compound formed.
The <em>+</em><em>3 charge of the cation Al+ will go to anion oxide O2- and the charge of anion -2 will go with cation Al+. </em>

Answer: reflected, clouds, greenhouse effect.
Explanation:
Sunlight can be absorbed, reflected , or scattered before it reaches Earth’s surface. About 30 percent of sunlight hits Earth directly, and 22 percent is filtered through clouds . Dust particles scatter short wavelengths, which causes the sky to appear blue. Earth radiates heat into the atmosphere, which traps the heat in gases, causing the greenhouse effect.
The correct answer is B) Basic. Hope this helps.
Answer:
The heat flow is best described as an exchange of heat between the system and the surroundings.
Explanation:
Heat is a form of energy which is transferred spontaneously from a hotter body to a cool body as a result of temperature differences between the substances. In the problem , it can be said that heat moves from the surroundings which may be a fractured knee of the athlete to the ice packs.
