Question

create the formula for magnesium phosphate by dragging and dropping the appropriate symbols into the large boxes and the subscripts in the small
all choices will be used.
2 3 mg (po₄)

Explanation:

Step1: Determine the charges

Magnesium (\(Mg\)) has a charge of \(+2\) (\(Mg^{2+}\)). Phosphate (\(PO_{4}\)) has a charge of \(-3\) (\(PO_{4}^{3 -}\)).

Step2: Use the criss - cross method

To balance the charges, we take the absolute value of the charge of one ion as the subscript of the other ion. So, for \(Mg^{2+}\) and \(PO_{4}^{3 -}\), we get \(Mg_{3}(PO_{4})_{2}\)

Answer:

\(Mg_{3}(PO_{4})_{2}\)
