Maximum ! if copper metal pieces were added to an aqueous solution of silver nitrate, the silver would be replaced in a single replacement reaction forming aqueous copper (ii) nitrate and solid silver. 1. write a balanced chemical equation for the reaction.2. how much silver is produced is 15.00 grams of cu is added to the solution of excess silver nitrate? 3. if silver metal sells for $4.50/ounce, how much would the silver collected be worth? (1 gram = 0.0353 oz)

  1.The balanced  chemical equation is as below

Cu +  2 Ag(NO)₃ → Cu(NO₃)₂  +2 Ag

2.The  much silver  produced  is  50.9 g

Step 1: find the  moles of Cu

moles =  mass÷  molar mass

  from periodic table the molar mass of Cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236  moles

Step 2: use the mole ratio to determine the  moles of Ag

from equation above   Cu:Ag  is 1:2

therefore the moles of Ag   =0.236  moles  x 2/1 =0.472  moles

Step 3: find the mass  of Ag

mass = moles x molar mass

from periodic table  the molar mass of Ag =107.87 g/mol

mass  = 0.472  moles x 107.87 g/mol = 50.9 g

3.  The  much  silver  collected worth is  1.797 oz

 convert  50.9 g  to oz

that is  1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1  gram}  =1.797 oz

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
