When a system at equilibrium is disturbed by a change in concentration of one of the components, it reacts in the direction that

reduces the change. Example: A(g) + B(g) ⇋ C(l) + D(s) So if the concentration of A is increased the reaction will proceed to use up more A in essence reducing the concentration of B and increasing the concentration of C and D. If the concentration of C is increased, there is no change since C is a liquid and is not part of the equilibrium constant expression. If the concentration of B is reduced the reaction will proceed to make more B and thus make more A as well. If the concentration of D is decreased, there is no change since D is a solid and is not part of the equilibrium constant expression. To improve air quality and obtain a useful product, chemists often remove sulfur from coal and natural gas by treating the contaminant hydrogen sulfide with O2: 2H2S (g) + O2 (g) ⇋ 2S (s) + 2 H2O(g) 1. What happens to the concentration of water if O2 is added? 2. What happens to the concentration of H2S if O2 is added? 3. What happens to the concentration of O2 if H2S is removed? 4. What happens to the concentration of H2S if sulfur is added?

Identify the substances that will appear in the equilibrium constant expression for the equation: 2Ag+(aq)+Zn(s)<->Zn2+(aq
Simora [160]

Hey there!


We Know that:



 2 Ag⁺(aq) + Zn(s) <-> Zn²⁺(aq)+2 Ag(s)


The equilibrium expression for the reaction is:



Kc =  [ Zn⁺² ]  /  [Ag⁺ ]²


Hope that helps!

Which of the elements listed below is most likely to exhibit an expanded octet in its compounds? o na c n s?
myrzilka [38]
Among the elements listed below, Sulfur (S) is the one that is most likely to exhibit an expanded octet in its compounds. It is included in the exceptions in the Octet Rule. For example, SF6, the sulfur atom has 6 bonds connected to it. It has a total of 12 electrons surrounding it rather than 8 electrons only.
