What is the mass-action expression Qc for the following chemical reaction:Zn(s)+2Ag+(aq) ⇌ Zn+2(aq)+2Ag(s) a. [Zn-2]/[Ag-]b. [
sattari [20]

Answer : The expression for reaction quotient will be :

Q_c=\frac{[Zn^{2+}]}{[Ag^{+}]^2}

Explanation :

Reaction quotient (Qc) : It is defined as the measurement of the relative amounts of products and reactants present during a reaction at a particular time.

The given redox reaction is :

2Ag^{+}(aq)+Zn(s)\rightarrow 2Ag(s)+Zn^{2+}(aq)

In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.

The expression for reaction quotient will be :

Q_c=\frac{[Zn^{2+}]}{[Ag^{+}]^2}

Assume that 8.5 L of iodine gas (I2) are produced at STP according to the following balanced equation:2KI(aq) + Cl2(
Aliun [14]

Answer: 0.3794 moles of Iodine gas are produced.

Explanation:

2KI(aq)+Cl_2(
g)\rightarrow 2KCl(aq)+I_2

Volume of iodine gas produced at STP =8.5 L

At STP, the 1 mol of gas occupies volume = 22.4 L

So, 8.5 L of volume will be occupied by:\frac{1}{22.4 L}\times 8.5=0.3794 moles

0.3794 moles of Iodine gas are produced.
