Copper reacts with silver nitrate through single replacement. if 2.75 g of silver are produced from the reacti? if 2.75 g of silver are produced from the reaction, how many moles of copper(ii) nitrate are also produced? how many moles of each reactant are required in this reaction?

Explanation:

a) Balanced equation

We know we will need an equation with masses and molar masses, so let’s gather all the information in one place.  

M_r:    63.55    169.87         187.56      107.87

             Cu  +  2AgNO₃ ⟶ Cu(NO₃)₂ + 2Ag

m/g:                                                          2.75

(b) Moles of Cu(NO₃)₂

(i) Calculate the moles of Ag

(ii) Calculate the moles of Cu(NO₃)₂

The molar ratio is 1 mol Cu(NO₃)₂:2 mol Ag

(c) Moles of Cu

The molar ratio is 1 mol Cu:2 mol Ag

(d) Moles of AgNO₃

The molar ratio is 2 mol Ag:2 mol AgNO₃

a. a clone will be physically identical to the original, but won’t be genetically identical
