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
The law of conservation of mass maintains that in all chemical reactions mass is conserved, this ensures that chemical reactions are balanced.
<h2>What is the law of conservation of mass?</h2>
It is a principle of chemistry that states that the quantities of the masses involved in a given reaction must be constant, that is, the quantity of reactants consumed is equal to the quantity of products formed.
<h3>Characteristics of the law of conservation of mass:</h3>
- The chemical composition of a substance remains constant.
- In a chemical reaction certain coefficients are used to balance the equation and this will allow the number of atoms to be equal on both sides.
Therefore, we can conclude that the law of conservation of mass is the one that holds that, within a closed system, the amount of matter before and after a transformation is always the same.

i think 12000 is the answer
I think the correct answer from the choices listed above is option B. <span>24 mL of Mg burn in 32 mL O2 to produce 56 mL of MgO </span>does not show the law of conservation of mass. Volumes cannot be added because there are volume effects when you add different substances. So, the reactants is not equal to the product.
