Answer:
Reaction is shifting left toward reactant side
Explanation:
4CuO(s) + CH₄(g) <=?=> CO₂(g) + Cu(s) + 2H₂O(g)
--------- 0.22M 0.67M ------- 1.30M
Qc = [O₂(g)][H₂O(l)]²/[CH₄(g)] = (0.67)(1.30)²/(0.22) =5.12
Kc = 1.1 < Qc = 5.12 => Reaction is shifting LEFT and reactant concentrations are increasing with product concentrations decreasing. Qc will be decreasing and final Kc value will be lower than original Qc upon reaching equilibrium stability.

FYI Note => For reaction mixtures the following is a good guide to reaction response to applied system stress. Note the conclusion follows the direction the inequality symbol is pointing.
Kc < Qc => Rxn system is shifting Left
Kc = Qc => Rxn system is at equilibrium
Kc > Qc => Rxn system is shifting Right
A would be the answer to this question
Answer:
The amount of Co2 generated is 15 moles
Explanation:
It bears the same ratio with Carbon meaning oxygen was used in excess
50ml = 50cm³ = 0,05dm³
C = n/V
n = 0,15 mol/dm³ × 0,05dm³
n = 0,0075 mol CH₃COOH
..............................
CH₃COOH + NaOH ----> CH₃COONa + H₂O
1 mol...............1 mol
1 mol CH₃COOH ------------1 mol NaOH
0,0075 mol CH₃COOH --- X
X = 0,0075 mol NaOH
V = n/C
V = 0,0075/0,1
V = 0,075 dm³ = 75cm³ = 75 mL
