Answer:
Keq = [H₂]⁴[CSe₂]/[CH₄][H₂Se]².
Explanation:
- The equilibrium constant expression is the ratio of the concentrations of the products over the reactants.
<em>CH₄(g) + 2H₂Se(g) ⇄ 4H₂(g) + CSe₂(g).</em>
<em></em>
<em>∴ Keq = [products]/[reactants] = [H₂]⁴[CSe₂]/[CH₄][H₂Se]².</em>
An electron
there is no table but an electron has a charge of -1

Answer: B) You are to continue heating the round-bottom flask until all liquid has been distilled.
Explanation:
Fractional distillation refers to a method that's useful for the separation of mixtures of solvents whereby there is less than 40°C in the boiling point difference.
With regards to the options given, the incorrect statement about the procedure for distillation is that you are to continue heating the round-bottom flask until all liquid has been distilled. This isn't correct.
