What are the formulas of the compounds cobalt(III)sulfate and manganese(II)hydroxide?

Question

Quizplus · Accepted Answer

- Cobalt(III)sulfate's formula can be obtained from the name: cobalt(III) means cobalt has a +3 charge, and sulfate is SO4. Therefore, the formula is Co2(SO4)3.
- Manganese(II)hydroxide's formula can be obtained from the name: manganese(II) means manganese has a +2 charge, and hydroxide is OH. Therefore, the formula is Mn(OH)2.
- Option A is incorrect because it has extra (S1U1B13), (S1U1B14), and (SOS1U1B14) subscripts that do not indicate anything meaningful.
- Option B is incorrect because it has an extra S1U1B12 subscript in the hydroxide formula, which does not correspond to any element.
- Option D is incorrect because it has an OH group with the wrong subscript (S1U1B12 instead of S1U1B-1).
- Option E is incorrect because it has a missing subscript for OH (S1U1B-1 instead of S1U1B12).
