Answer:
Pyruvic acid: conjugate base
Lactic acid: conjugate base
Explanation:
The ratio of conjugate base to conjugate acid can be found using the Henderson-Hasselbalch equation when the pH and pKa are known.
pH = pKa + log([A⁻]/[HA])
The equation can be rearranged to solve for the ratio:
pH - pKa = log([A⁻]/[HA])
[A⁻]/[HA] = 10^(pH-pKa)
Now we can calculate the ratio for the pyruvic acid:
[A⁻]/[HA] = 10^(pH-pKa) = 10^(7.4 - 2.50) = 79433
[A⁻] = 79433[HA]
There is a much higher concentration of the conjugate base.
Similarly for lactic acid:
[A⁻]/[HA] = 10^(pH-pKa) = 10^(7.4 - 3.86) = 3467
[A⁻] = 3467[HA]
For lactic acid the conjugate base also dominates at pH 7.4
First you find the molar mass of the formula.
3C: 36.03g + 8H:8.08g + N: 14.01g + 5O: 80g + P: 30.97g = 169.09g
Then do the mole ratio (304.3g)x(1mole/169.09g) = 1.800 moles
The answer is C, Sugar.
An array of chemical reactions done by plants to transform energy from the Sun into chemical energy, that is, in the form of sugar is known as photosynthesis. Primarily, the plants utilize sunlight's energy to react water and carbon dioxide to generate glucose (sugar) and oxygen. In plants, the process of photosynthesis takes place in the chloroplasts.
Answer:
The answer to that question is 24 AMU.
Explanation:
I know this because i got the answer correct on the quiz. To get the average, you just add the 4 atomic masses given to you together then divide by 4.
