When copper wire is placed into a silver nitrate solution, silver crystals and copper(II) nitrate solution form. Write the balanced chemical equation for the reaction. (Type your answer using the format CH4 for CH4.)
1 Cu(s) + 2AgNO3(aq = 2Ag(s) + 1Cu(NO3)2(aq)
If a 23.5 g sample of copper is used, determine the theoretical yield of silver.
The equation you have written for the reaction between Cu and Ag^+ is correct; however, you don't need the coefficient of 1 for Cu and Cu(NO3)2.
For the theoretical yield part, I don't get 9 g; I am unable to determine if that is a typo or not.
1. Convert 23.5 g Cu to moles. moles = grams/molar mass.
2. Using the coefficients in the balanced equation, convert moles Cu to moles Ag.
3. Now convert moles Ag to grams. grams = moles x molar mass.
