4. Cu(NO)2

Hello!

2.

From the formula , we see the element Sodium (Na) and Sulfite ( ).

We can write the chemical name simply by combining the two names above:

3.

With the given formula, we can identity Copper (Cu) and Nitrite ().

Remember, since Copper is a transition metal, we must identify the charge in the chemical name. Do so using roman numerals.

Since has a charge of -1 and there are two molecules in this formula, then it has a total charge of -2.

Copper must have a charge of +2 for it to be neutral, so the chemical name will have a roman numeral of II:
