Answer:

CuBr

Mn2O3

Hg2I2

Mg3(PO3)2

Step-by-step explanation:

When writing the formula of an ionic compound, we use the exchange method.

The symbol of each element or ion is written with it's charge as a superscript. The charges are then interchanged, the signs are dropped and the figures are written as subscripts. This gives the formula of compound.
