Answer:
(K) = [H2] [Cl2] / [HCl]²
Explanation:
The equation of the reaction is given as;
2 HCl (g) ⇔ H2 (g) + Cl2 (g)
The Equilibrium constant is the ratio of the concentration of the products and reactants raised to the power of their coefficients
Products = H2 and Cl2
Reactants = HCl
Equilibrium constant (K) = [H2] [Cl2] / [HCl]²
In my opinion the answer is D
Answer:
I believe it to be a difference in isotopes.
Explanation:
This is because since both are the same element it cannot be allotropes which are on a molecular level so it must be isotopes.

The correct answer is (B) Adding a dilute solution of HCl
<u>EXPLANATION</u>
The presence of carbonate ions can be tested by adding a dilute acid to the solution. The acid displaces Carbon (IV) oxide from the solution. Using HCl, and a carbonate of metal X.
XCO₃₍s₎ + 2HCl₍aq₎⇒ XCl₂₍aq₎+ H₂O₍l₎ + CO₂₍g₎
The gas produced is tested using calcium hydroxide to confirm whether it is carbon (IV) oxide.
