<h3>
Answer:</h3>
156 calories
<h3>
Explanation:</h3>
- Carbohydrates, proteins and fats are food substances used by living organisms to generate energy required for the day to day activities.
- They supply energy which differs per gram for each food substance.
- That is;
1 g of carbohydrate = 4 calories
1 g of fat = 9 calories
1 g of protein = 4 calories
Therefore, whole milk serving containing 8.0 g of fat, 8.0 g of protein and 13 g of carbohydrates will contain the following number of calories;
8.0 g of fat = 8 g × 9 cal/g = 72 calories
8.0 g of protein = 8 g × 4 cal/g = 32 calories
13 g of carbohydrates = 13 g × 4 cal/g = 52 calories
Total amount of energy = 156 calories
Therefore, an 8 oz serving of whole milk contains 156 calories
Answer : The correct option is, (2) Energy is absorbed as bonds are broken.
Explanation :
As we know that the bonds are formed and breaks during the chemical reaction. Some energy is released or absorbed when the bonds are formed and breaks during the chemical reaction.
During the bond breaking, some energy is required to break the bonds.
During the bond formation, some energy is released to the formation of the bonds.
In the given reaction, the bond between the hydrogen-hydrogen in 
are breaking into two hydrogen. That means during the bond breaking, some energy is required or absorbed to break the bonds.
Hence, the correct option is, (2) Energy is absorbed as bonds are broken.
