When calcium metal (Ca) reacts with oxygen has (O2), it produces the ionic compound calcium oxide (CaO). Write the balanced equation for this reaction. Then, explain if this process meets the requirements to be considered a redox reaction

2Ca + O2 → 2CaO

Please find the explanation below

Explanation:

According to the question, Calcium metal (Ca) reacts with Oxygen (O2) gas to form Calcium oxide (CaO). The balanced chemical equation as follows:

2Ca (s) + O2 (g) → 2CaO (s)

An oxidation-reduction reaction (redox) is a type of reaction that involves the change of oxidation number of the elements/ions due to gain or loss of electrons. This reaction described above is an example of oxidation reduction (redox) reaction because:

- Calcium atom loses two electrons to form Calcium ion (Ca²+) while Oxygen atom gains two electrons to form Oxygen ion (O²-). The two ions (calcium and oxygen) combine to form the neutral ionic compound: CaO.

Calcium transfers two electrons to oxygen, hence, calcium is oxidized while oxygen is reduced. This event confirms that this reaction meets the requirements to be considered a redox reaction.

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.
