What types of reactions are these?
2Mg + O2 = 2MgO
Zn + 2HCl(aq) = ZnCl2 + H2
2H2O2(aq) = 2H2 + 2O2
Fe + CuSO4 (aq) =FeSO4 + Cu
Pb(NO3)2 (aq) +H2SO4 (aq) = PbSO4 + 2HNO3
CaCO3 (s) + 2HCl (aq) = H2O+CaCl2+CO2
CuSO4.5H2O (s) = CuSO4 + 5H2O
Na2O(s) + H2O = 2NaOH
FeSO4 (aq) + KMnO4 (aq) =
Na2CO3 (aq) + 2HCl (aq) = 2NaCl + H2O + CO2
Thanks

2Mg + O2 = 2MgO single replacement
Zn + 2HCl(aq) = ZnCl2 + H2 single replacement
2H2O2(aq) = 2H2 + 2O2 decomposition
Fe + CuSO4 (aq) =FeSO4 + Cu single replacement
Pb(NO3)2 (aq) +H2SO4 (aq) = PbSO4 + 2HNO3 double replacement
CaCO3 (s) + 2HCl (aq) = H2O+CaCl2+CO2 double replacement

CuSO4.5H2O (s) = CuSO4 + 5H2O decomposition
Na2O(s) + H2O = 2NaOH single replacement
FeSO4 (aq) + KMnO4 (aq) =
Na2CO3 (aq) + 2HCl (aq) = 2NaCl + H2O + CO2 double replacement

I have only been here answering questions a couple of days now and no one has asked this much.

You are simply choosing not to do your homework and trying make us do it for you. Some of us won't be used like that.

You need to make an atempt to do it first and perhaps post what you think they are and then ask us to check and see if you are right. Not just give us 10 questions to do for you. You won't learn anything that way. If you wouldn't ask your teacher to do it then don't ask us to either.

These are all oxidation reduction reactions also known as redox reactions because their oxidation number has changed.
