Study this chemical reaction: cr o2 -> cro2 then, write balanced half-reactions describing the oxidation and reduction that happen in this reaction.

Oxidation: Cr → Cr⁴⁺ + 4 e⁻

Reduction: 4 e⁻ + O₂ → 2 O²⁻

Explanation:

Let's consider the following redox reaction.

Cr + O₂ → CrO₂

Cr is oxidized. Its oxidation number increases from 0 to +4. The corresponding half-reaction is:

Cr → Cr⁴⁺ + 4 e⁻

O is reduced. Its oxidation number decreases from 0 to -2. The corresponding half-reaction is:

4 e⁻ + O₂ → 2 O²⁻

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .
