What is the correct equilibrium constant expression for the following heterogeneous equilibrium? 4HCl (g) + O2 (g) ⇄ 2H2O (l) +
gizmo_the_mogwai [7]

Answer:

Kc=[Cl2]2/[HCl]4[O2]

Explanation:

Hello,

In this case, the law of mass action, allows us to study the mathematical expression regarding an equilibrium chemical reaction allowing us to see a relationship between the equilibrium constant and the concentration of both the products and reactants at equilibrium for either gaseous or aqueous substances only. Such relationship is assembled as the quotient between the concentration of products at equilibrium over the concentration of reactants at equilibrium equaling the equilibrium constant. Thus, for the given chemical reaction, such expression will have the concentration of chlorine at the numerator and both the concentrations of hydrogen chloride and oxygen at the denominator since water is liquid so it is not included in the shown below equation:

Kc=\frac{[Cl]^2}{[HCl]^4[O_2]}

Therefore the answer is: Kc=[Cl2]2/[HCl]4[O2].

Best regards.

Which part of the calcium atom in the ground state is represented by the dots in its Lewis electron dot diagram
zysi [14]

Answer:

On the left side of calcium atom.

Explanation:

There are two dots are present on the left side of calcium atom which represents the unpaired electrons present in the outermost shell. This structure is presented by Lewis in order to show the number of unpaired electrons in the atom. if the calcium atom loses these two electron during a chemical reaction so the two dots disappear and the calcium atom is now stable.
