Question

Predict the chemical formulas of the compounds formed by the 
following pairs of ions: (c) Na+ and Cr2O72-

Accepted Answer

Hey everyone, we're asked to provide the chemical formula of the compound when we combined rubidium with a plus one charge and oxalate with a -2 charge. To answer this question, we can go ahead and use our Criss cross method and criss cross our charges. So we're going to end up with rubidium too, and oxalate as is. And this will be our final formula. So I hope this made sense and let us know if you have any questions.
