I already know how to do question #1 but I need help with question #3 and you need the answers from #1 to answer #3. I already solved question #1 so that you could help with #3

 

1. Balance each of the following equations:
 
A. __1_ Cu(s) + __4_ HNO3(aq) → _1__ Cu(NO3)2(aq) + _2__ NO2(g) + _2__ H2O(l)
 
 
B. _1__ Cu(NO3)2(aq) + __2_ NaOH(aq) → _1__ Cu(OH)2(s) + _2__ NaNO3(aq)
 
 
C. _1__ Cu(OH)2(s) → __1_ CuO(s) + __1_ H2O(l)
 
 
D. _1__ CuO(s) + _1__ H2SO4(aq) → _1__ CuSO4(aq) + __1_ H2O(l)
 
 
E. __1_ CuSO4(aq) + __1_ Zn(s) → _1__ Cu(s) + _1__ ZnSO4(aq)
 
 
 

3. If you measured out 100.0 mg of copper wire, calculate the exact amount of zinc that you would need in Part E of the experiment to complete the copper cycle. (Hint: use your balanced equations from Question 1.)
