Answer 1

6. CCl_4

7. H_2O_2

8. SeO_6

Step-by-step explanation:

They are all nonmetal chemical formulas, so they call for the nonmetal naming rules. (It's basically just memorizing the roots: mono, di, tri, tetra, penta, hexa, septa, octa, nona, deca).

These are the rules for molecular/covalent naming:

-First element starts with the element name

-Second element has -ide

-Use prefixes to show the nuber of atoms of each part

-Don't use "mono" on the first element.

-If there is a word with "ao"" or "oo", just turn it into "o"

Ex: CaO is not "calcium monooxide", it's just "calcium monoxide"
