Linear
Soccer ball
Ring
Cone like



5: Hydrocarbons with double bonds are generally considered:
Alkanes
Alkynes
Alkenes
Aromatics



6: The fundamental building blocks of proteins are:
Enzymes
Polypeptides
Nucleic acids
Amino acids




7: The carbon compounds best know as catalysts that fit other compounds like puzzle pieces are:
Enzymes
Polypeptides
Nucleic Acids
Amino Acids

Answer 1

1. All of these. (Carbon dioxide in the air, coal in the ground, and all that seafood in the ocean.)

2. Carbon's bonding ability. (Carbon forms four covalent bonds.)

3. Pyrite. (Pyrite is iron sulfide, fool's gold, FeS2.)

4. Ring.

5. Alkenes. With an "e".

(Although aromatic compounds were drawn with double bonds in the olden days, a ring within a hexagon is preferred today. Even when drawn with double bonds, it is understood the aromatic bond is different than a single and a double bond.)

6. Amino acids. Approx. 20 different amino acids are used to make proteins. For more information, see my web site at:

7. Enzymes.

Answer 2

1. All of these.
2. Bonding ability- it can form long chains and other complex structures, which most other elements can't.
3. Pyrite. That's an iron oxide.
4. Aromatics form rings with alternating single and double bonds.
5. Alkenes have double bonds. Of course, so do aromatics.
6. Nucleic acids. Proteins are just chains of them.
7. Enzymes.
You really ought to do your own homework though.

Sorry for 1 not sure

Answer 4

You won't learn if you don't do your homework yourself
