0.750l = 750ml
14% of 750ml is 105
therefore, the 750ml bottle of wine has 105ml of alcohol
Chemical energy is converted to thermal energy.
Answer:
![C_{17}H_{18}FN_3O_3](https://tex.z-dn.net/?f=C_%7B17%7DH_%7B18%7DFN_3O_3)
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
<u>3. Fluorine atoms</u>
