plese help me solve these questions

Question:1

There are six equations given in the experimental procedure.  Balance these equations below and transfer your results to the appropriate place in the experimental procedure. (Hint: The coefficient on HNO3 in reaction one is 4.)

(1)   Cu(s)  +      HNO3(aq)   ?      Cu(NO3)2(aq)  +      NO2(g)  +      H2O(l)

(2)   Cu(NO3)2(aq)  +      NaOH(aq)  ?      Cu(OH)2(s)   +      NaNO3(aq)

(3)   Cu(OH)2(s)   +  heat   ?      CuO(s)  +      H2O(l)

(4)   CuO(s)  +      H2SO4(aq)  ?      CuSO4(aq)  +      H2O(l)

(5)   CuSO4(aq)  +      Al(s)  ?      Al2(SO4)3(aq)  +      Cu(s)

(6)   Al(s)  +      HCl(aq)  ?      H2(g)  +      AlCl3(aq)

Question:2

Define the following (if necessary, see the glossary of your book):

a)  oxidation

b) reduction

c)  redox (oxidation reduction) reaction

d)  exchange (metathesis) reaction

e)  precipitation reaction

f)  displacement (single-replacement) reaction

g)  decomposition reaction

Question:3

Which of the reaction(s), 1 through 6, given in the experimental procedure would be classified as:

(Some reactions may be classified in more than one way.)

a)  exchange (metathesis) reaction(s)?

b)  precipitation reaction(s)?

c)  displacement (single-replacement) reaction(s)?

d)  decomposition reaction(s)?

e)  redox (oxidation-reduction) reaction(s)?

Question:4

Choose one of the reactions classified as a redox reaction and identify the element that is oxidized and the element that is reduced.  Also indicate the initial and final oxidation numbers of the atoms of the elements that undergo oxidation and reduction
