It should be 24 electrons
Answer:
Potassium cation = K⁺²
Explanation:
The metal cation in K₂SO₄ is K⁺². While the anion is SO₄²⁻.
All the metals have tendency to lose the electrons and form cation. In given compound the metal is potassium so it should form the cation. The overall compound is neutral.
The charge on sulfate is -2. While the oxidation state of potassium is +1. So in order to make compound overall neutral there should be two potassium cation so that potassium becomes +2 and cancel the -2 charge on sulfate and make the charge on compound zero.
2K⁺² , SO₄²⁻

Answer:
I think air is more denser than oxygen
The reaction will proceed in the reverse direction in order to increase the concentrations of both CO and H2O and decrease that of CO2 and H2 until Q = K.
The reaction will proceed to the left
Step 1: The balanced equation
CO(g) + H2O(g) ⇌ CO2(g) + H2(g)
Step 2: Data given
Kp = 2.7
Number of moles of CO = 0.13 mol
Number of moles of H2O = 0.56 mol
Number of moles of CO2 = 0.62 mole
Number of moles of H2 = 0.61 mol
Volume = 2.0L
Step 3: Calculate Q
Pco = 0.13 / 1.92 P
Ph2o = 0.56 / 1.92 P
Pco2 = 0.62/1.92 P
Ph2 =0.61 / 1.92 P
Q = [CO2][H2] / [CO][H2O] = 5.2
Q > Kp The reaction will proceed to the left
The reaction will proceed in the reverse direction in order to increase the concentrations of both CO and H2O and decrease that of CO2 and H2 until Q = K.
