Answer 1

The chemical formula for a compound made up of one phosphorus atom, three fluorine atoms, and one oxygen atom is PF3.

Step-by-step explanation:

A certain compound made up of one phosphorus (P) atom, three fluorine (F) atoms, and one oxygen (O) atom is called phosphorus trifluoride. The chemical formula for this compound is PF3.

Answer 2

Answer: The chemical formula for the given compound is
`PF_3O`

Step-by-step explanation:

We are given:

A chemical compound has 1 phosphorus atom (P), 3 fluorine atoms (F) and 1 oxygen atom (O).

The chemical formula will contain as many number of atoms, as the given ones.

Thus, the chemical formula for the given chemical compound is
`PF_3O`

This compound is named as phosphoryl fluoride.
