Because the force and it hard
The law of conservation of energy states that energy can neither be created nor destroyed.
It can only be converted from one form of energy to another.

Answer:
it means compound A is <u>less</u> polar than compound B
Explanation:
It is sure that the more polar the solvent, the faster compounds elute, regardless of the compounds polarity. This means changing the solvent polarity cannot change the order compounds elute from a TLC or column. This may seem non intuitive, as it would seem that a polar solvent would move a polar compound farther than a nonpolar compound.

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
