Chemical Reaction types?

Question

Two of my answers below are incorrect, but I don't know which ones.

1) CuO(s) + HCl(aq)---> CuCl2(aq) + H2O(l)
My answer: double replacement

2) 2Al(s) + 3Br2(g) ---> 2AlBr3(s)
My answer: combination

3) 2C2H2(g) + 5O2(g) ---> 4CO2(g) + 2H2O(g)
My answer: combustion

4) Pb(NO3)2(aq) + 2NaCl(aq) ---> PbCl2(s) + 2NaNO3(aq)
My answer: double replacement

5) 2Mg(s) + O2(g) ---> 2MgO(s)
My answer: combustion

6) Fe2O3(s) + 3C(s) ---> 2Fe(s) + 3CO(g)
My answer: single replacement

7) C6H12O6(aq) ---> 2C2H6O(aq) + 2CO2(g)
My answer: decompostion and combustion

8) BaCl + KCO ---> BaCO + 2KCl
My answer: double replacement

Some answers in the answer bank, but I didn't use are:
-Decomposition
-Single replacement and combination
-Double replacement and single replacement
-Other type of reaction
-Combination and decomposition
-Oxidation reduction reaction
-Combination and combustion.
-Neutralization

THANKS VERY MUCH.

Answer 1

The first one is Acid Base.

Answer 2

5) is oxidation

7) is decomposition

Answer 3

i imagine your question's been spoke back already, yet whats up, from my perspective, i imagine redox reactions ore double displacement reactions are the prime for sophistication projects! :) sturdy good fortune...
