<span>The answer is c - physical activity and exercise typically lead to higher energy levels. The endorphins and hormones released during periods of high activity actually help to combat stress and depression linked to a depletion in serotonin, and therefore can only increase the quality of life. The other possible answers to this question are therefore all incorrect.</span>
You forgot one...and that happens to be the answer---> Accuracy
I'm not quiet sure...possibly an ionic bond.
Answer:
To react with 0.5 moles of Zn 1 mole of HCl is required
Explanation:
Given data:
Number of moles of Zn = 0.50 mol
Number of moles of HCl = ?
Chemical equation:
Zn + 2HCl → H₂ + ZnCl₂
Now we will compare the moles of Zn and HCl through balance chemical equation.
Zn : HCl
1 : 2
0.50 : 2×0.5 = 1 mol
In order to react with 0.5 moles of zinc 1 mole of HCl is required.
There are 22.5 grams of protein in one cup of soup that has 140 kcal with 8 g of carbohydrate and 2 g of fat.
<h3>What is the mass of a substance?</h3>
The mass of a substance is the quantity of the substance that is being measured in grams or kilograms.
To determine the energy from the 8g of carbohydrate, we have:
= 8g × 4 kcal/g (the corresponding calories of food type)
= 32 kcal
The energy from 2g of fat = 2g × 9 kcal/g
= 18 kcal
The energy from protein is calculated as:
= 140 kcal - 32 kcal - 18 kcal
= 90 kcal
The required mass of the protein in grams is:
![\mathbf{= 90 \ kcal \times \dfrac{1}{4 \ kcal }}](https://tex.z-dn.net/?f=%5Cmathbf%7B%3D%2090%20%5C%20kcal%20%5Ctimes%20%5Cdfrac%7B1%7D%7B4%20%5C%20%20kcal%20%7D%7D)
= 22.5 grams
Therefore, we can conclude that there are 22.5 grams of protein in one cup of soup.
