Here are some rules:
1. The oxidation state of a free element (uncombined element) is zero.2. For a simple (monatomic) ion, the oxidation state is equal to the net charge on the ion.3. Hydrogen has an oxidation state of +1 and oxygen has an oxidation state of −2 when they are present in most compounds.
The oxidation number of Fe in Fe(NO3)2 is +3.

Answer:
Explanation:
In the figure attached, I have numbered the carbon atoms to permit to count them easily.
<u>1. Carbon atoms</u>
Each vertex without a letter represents a carbon atom:
- Count them: 17 (they are numbered on the figure attached)
<u>2. Hydrogen atoms</u>
For each carbon subract 1 for each bond and subtract 1 for each group attached to it:
- Carbon 1: 4 - 2 = 2
- Carbon 2: 4 - 2 = 2
- Carbon 3: 4 - 2 = 2
- Carbon 4: 4 - 2 = 2
- Carbon 5: 4 - 4 = 0
- Carbon 6: 4 - 4 = 0
- Carbon 7: 4 - 3 = 1
- Carbon 8: 4 - 4 = 0
- Carbon 9: 4 - 4 = 0
- Carbon 10: 4 - 3 = 1
- Carbon 11: 4 - 4 = 0
- Carbon 12: 4 - 4 = 0
- Carbon 13: 4 - 3 = 1
- Carbon 14: 4 - 3 = 1
- Carbon 15: 4 - 2 = 2
- Carbon 16: 4 - 2 = 2
- Carbon 17: 4 - 4 = 0
Total H atoms attached to C atoms:
- 2 + 2 + 2 + 2 + 1 + 1 + 1 + 1 + 2 + 2 = 16
Total H atoms in all: 16 + 2 = 18
