Answer:
on average, an ATP molecule turn over is between 500 and 750 times
Explanation:
The ATP molecule is hydrolyzed and resynthesized depending on the macromolecules intake (carbohydrates, proteins and lipids) an the energy required by the organism (for excercise, grow, heal, etc)
Answer:
FALSE
Explanation:
Keratinocytes begin to die in the stratum granulosum is False.
<u>Answer:</u> The partial pressure of hydrogen is 705.9 mmHg
<u>Explanation:</u>
Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.
To calculate the partial pressure of hydrogen gas, we use the law given by Dalton, which is:
![P_T=p_{H_2}+p_{H_2O}](https://tex.z-dn.net/?f=P_T%3Dp_%7BH_2%7D%2Bp_%7BH_2O%7D)
We are given:
Total pressure of the collection tube,
= 729.8 mmHg
Vapor pressure of water,
= 23.8 mmHg
Putting values in above equation, we get:
![729.7=p_{H_2}+23.8\\\\p_{H_2}=729.7-23.8=705.9mmHg](https://tex.z-dn.net/?f=729.7%3Dp_%7BH_2%7D%2B23.8%5C%5C%5C%5Cp_%7BH_2%7D%3D729.7-23.8%3D705.9mmHg)
Hence, the partial pressure of hydrogen is 705.9 mmHg
Answer:
538L of carbon dioxide will be produced
Explanation:
This is a classic example of combustion of an alkane.
If balanced equation is not given; this format can come in handy.
For any alkane of the type : CₙH₂ₙ₊₂ , it's combustion reaction will follow:
2CₙH₂ₙ₊₂ + (3n+1) O₂ → (2n)CO₂ + 2(n+1) H₂O
For ethane:
2C₂H₆(g) + 7O₂(g) → 4CO₂(g) + 6H₂O(l)
Here, 2 mole of ethane gives 4 moles of CO₂.
or,
of ethane gives
of CO₂.
Then, 269L of ethane will give:
= ![\frac{269 \times 4 \times 22.4}{2 \times 22.4}](https://tex.z-dn.net/?f=%5Cfrac%7B269%20%5Ctimes%204%20%5Ctimes%2022.4%7D%7B2%20%5Ctimes%2022.4%7D)
=
L
= 538 L
Therefore, 538L of carbon dioxide will be produced
