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!

If the concentration of the stock (provided) Cu(NH3)42 was 0.041 M, what concentration will the Cu2 be in beaker?

kodGreya [7K]

Answer:

$[Cu^{2+}]=0.041 M$

Explanation:

Hello!

In this case, since the molarity of a solution is defined in terms of the moles of the solute and the volume of solution, given that the concentration of Cu(NH₃)₄²⁺ is 0.041 M, and there is only one copper atom per Cu(NH₃)₄²⁺ ion, we can compute the concentration of Cu²⁺ as shown below:

$[Cu^{2+}]=0.041\frac{molCu(NH_3)_4^{2+}}{L}*\frac{1molCu^{2+}}{1molCu(NH_3)_4^{2+}} =0.041 \frac{molCu(NH_3)_4^{2+}}{L}$

$[Cu^{2+}]=0.041 M$

Best regards!

Identify the missing coefficient in the balanced equation and classify the type of reaction.

I think it is decomposition because it processes in which chemical species break up into simpler parts.
