Question

2 multiple choice 10 points what is the correct formula for manganese (iii) phosphate? mnpo₄ mn₃po₄ mn(po₄)₃ mn₄po₃

Explanation:

Step1: Determine the charge of manganese ion

Manganese (III) has a charge of \(Mn^{3+}\) (the Roman numeral III indicates +3 charge).

Step2: Determine the charge of phosphate ion

Phosphate ion is \(PO_{4}^{3 -}\).

Step3: Use the criss - cross method

To form a neutral compound, the charges must balance. For \(Mn^{3+}\) and \(PO_{4}^{3 -}\), the ratio is 1:1. So the formula is \(MnPO_{4}\).

Answer:

MnPO₄
