Suppose a chromium atom in the oxidation state formed a complex with one chloride anion and five water molecules. Write the chemical formula of this complex.

[CrCl(H₂O)₅]²⁺

Explanation:

Oxidation Number of Chromium = +3

Oxidation Number of Chloride = -1

Oxidation Number of Water molecules = 0

Since the complex contains one chloride atom (Cl), 5 water molecules (H₂O) and one chromium atom (Cr). We have;

CrCl(H₂O)₅

The oxidation number of the mixture is given as;

+3   + (-1)  + 5(0) = x

x = + 3 - 1 + 0

x = +2

The chemical formular of the complex is;

[CrCl(H₂O)₅]²⁺

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
