Answer:
bruh what is the question
Explanation:
there is no question ;-;
Answer : The balanced chemical reaction will be:
Explanation :
As per question when copper(II) oxide react with sulfuric acid then it gives copper(II) sulfate and water.
This reaction is known as double displacement reaction in which cation of two reactants exchange their places to give two different products.
The balanced chemical reaction will be:
In order for a cellular device to operate, it requires battery power, otherwise known as energy.
or you can do this
Us humans consume food so that we can have the sufficient energy to accomplish tasks.
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
