Predict the chemical formulas of the compounds formed by the following pairs of ions: (c) Hg22+ and CO32–
Alright guys, so here we have to predict the chemical formula. So we have mercury and carbonate. So we have to take a look at the charges. So here we have 2+ and here we have 2-. The numbers are equal.
If the numbers are equal that means that means they cancel each other out. So then our formula will simply be HG2CO3. This is assuming that the numbers are cancelled out. So this will be your final answer. Let's move on.
