Answer:
n=1,2,3,4
Explanation:
The electronic configuration of vandanium is
1s2 2s2 2p6 3s2 3p6 3d3 4s2
There are two electrons in n=1, eight electrons in n=2, eleven electrons in n=3 and two electrons in n=4
The theoretical mass of silver that will be produced is calculated as follows
write the reaction equation
Cu + 2Ag(No3) ---> 2Ag + Cu(NO3)2
calculated the moles of each reagent
moles =mass/molar mass
Cu = 6.51g/63.5g/mol= 0.103 moles
Ag(NO3)2 = 28.4 g/169.87g/mol = 0.167 moles
Cu is the limiting reagent therefore the moles Ag= 2 x0.167 = 0.334 moles
mass = moles xmolar mass
0.334mol x 107.87g/mol = 36.02 grams
