Copper reacts with silver nitrate through single replacement.

a. if 2.25 g of silver are produced from the reaction, how many moles of copper(ii) nitrate are also produced?
b. how many moles of each reactant are required in this reaction?

            i) 0.0418 mole Cu

            ii) 0.0209 mol Ag NO₃

Explanation:

1) Balanced chemical reaction (single replacement):

In a single replacement reaction a more acitve metal (Cu) replaces a less active metal (Ag)

2) Mole ratio:

3) Moles of Ag

4) Moles of copper(II) nitrate:

That is the answer of part a: 0.0104 moles copper(II) nitrate.

5) Moles of each reactant

i) Cu:

        1 mole Cu / 2 mole Ag = x / 0.0209 mol Ag

ii) Ag NO₃

       2 mole Ag NO₃ / 2 mole Ag = x / 0.0209 mole Ag
