D. The concentration for the B mixture is 0.5 M.
<h3>concentration for the B mixture</h3>
kc = [B]/[A]
where;
- kc is equilibrium constant
- A is the concentration for the A mixture
- B is the concentration for the B mixture
B = kc(A)
B = (5x 10²)(1 x 10⁻³)
B = 0.5 M
Thus, the concentration for the B mixture is 0.5 M.

Answer:
2 to 1
Explanation:
The reaction equation is given as:
2KHCO₃ → K₂CO₃ + CO₂ + H₂O
The conversion factor between the moles of KHCO₃ and K₂CO₃ is 2 to 1.
From the balanced chemical equation, we find out that;
2 moles of 2KHCO₃ will produce 1 mole of K₂CO₃.
So given any mole of either of the reactant or product, we can find the unknown.
Answer:
The answer is option D.
Explanation:
In balancing in acidic solutions, the oxygen is accounted for by adding a water molecule or H2O on the side that needs oxygen and 2H+ molecules for every H20 molecules placed on the other side of the equation.
The H+ and H2O molecules are in the ratio 2 : 1
