Answer 1

I'm only helping you because you seem to have done the rest of the questions!

1. Butene is C4H8

2. N and O are very close in the Periodic Table

3. NaBr contains a metal and a non-metal

4. Your diagrams have come out as unintelligible. Look for a molecule with a C=C double bond and no oxygen.

5. CO2 contains non-metals only.

6. Ethane is C2H6, and ethene is C2H4. So they both contain 2 C atoms.

17. See 3.

Answer 2

using the ^ for subscripts made the formulation seem overly crowded and complicated so I bumped off them. each type which you spot is a subscript. additionally, #s 4 and 15 are an identical... a million.
