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

Answer:
A. 21 J
Explanation:
Your temperature change is 10 degrees Celsius, or 10 Kelvin, it makes no difference either way.
Cp = 2.06 J/g•K
Multiply by the temperature change to just get J/g
2.06 J/g•K • 10 K = 20.6 J/g ≈ 21 J/g
Answer:
Terrestrial
-20 to 30 degrees celsius average
(20 – 35 inches) of rain per year.
