A certain compound is made up of one carbon (C) atom, two fluorine (F) atoms, and one oxygen (O) atom. What is the chemical formula of this compound?

CF₂O

Explanation:

To determine how the molecule will be made think about the valence number of each element in molecule:

 F= -1 , O= -2 , C= +4

because the C is positive atom it  will be the central atom with a double bond to the O and a single bond to each F.

this way all atoms completed the octet and stability

CH3BR

Explanation:

Hope this helps.
