Answer:
Reaction Quotient, Kq = {[a-ketoglutarate]x[L-alanine]}/{[L-glutamate]x[pyruvate]}
or, Kq = {(1.6x10-2)x(6.25x10∧-3)}/{(3x10∧-5)x(3.3x10-4)} = 1.01 x 10∧4
Since Kq > Keqb ; therefore the reaction will proceed in the backward direction, in order words the reaction will not occur in forward direction. i.e formation of reactants will be favored.
Explanation:
0.922 atm is the total pressure of gas mixture that contains oxygen, nitrogen and helium gases.
Explanation:
Data given:
partial pressure of the oxygen p
= 0.197 atm
partial pressure of the nitrogen gas p
= 0.461 atm
partial pressure of the helium gas pHe = 0.264
total pressure P in the gas mixture= ?
We know that individual gases exert pressure on the mixture of gases independently. From Dalton's law of pressure it is said that sum of partial pressure of all the gases in the mixture equals its total pressure. So,
Ptotal = p + p + pHe
putting the values in the mixture:
Ptotal = 0.197 + 0.461+ 0.264
Ptotal = 0.922 atm
Total pressure is 0.922 atm.
Oxygen was first produced via photosynthesis as ocean microbes evolved in the event that was called the Great Oxidation Event. Therefore the correct answer is C

The van't Hoff factor is the ratio between the amount of particles produced when a substance is dissolved and the amount of substance being dissolved. If ionization is 0 percent then it would mean that the substance do not dissociate into particles so the van't Hoff factor would be 1. However, when the percent ionization is 100%, then it fully dissociates into ions. For H2SO4 at 100% ionization, the vant hoff factor should be three, two hydrogen ions and one sulfate ion.
