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

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
