Question

Silver metal is placed in 0.653 moles of zinc nitrate. How many moles of zinc can be produced?

Answer 1

Given:

Silver metal is placed in 0.653 moles of zinc nitrate.

To find:

How many miles of Zinc can be produced?

Calculation:

First of all, let's imagine the equation:

$Ag + Zn(NO_{3})_{2}\rightarrow AgNO_{3}+Zn$

So, this above imaginary equation is not possible.

• This is simply because Silver (Ag) is less reactive that Zinc (Zn).

• Due to lesser reactivity, silver will never be able to displace zinc from zinc nitrate.

• Also , Silver lies below Zinc in the reactivity series.

So, zero moles of Zinc will be produced.

• However, opposite reaction is possible when zinc is added to Silver nitrate.
