Physcial Science Help!?
Please help me on the following. I already did it, but I want to check. Just predict the chemical reaction as an equation.
1.) Magnesium Bromide + Chlorine (Anionic Single Replacement)
2.) Aluminum + Iron (III) Oxide (Cationic Single Replacement)
3.) Silver Nitrate + Zinc Chloride (Double Replacement)
4.) Hydrogen Peroxide (Decomposition)
5.) Zinc + Hydrochloric Acid (Cationic Single Replacement)
6.) Sulfuric Acid + Sodium Hydroxide (Double Replacement)
7.) Sodium Hydrogen (Synthesis)
8.) Acetic Acid + Copper (Cationic Single Replacement)
I know these might take a while, but I need help. I think I did some wrong.

1) MgBr2 + Cl2 ---> MgCl2 + Br2
2) Al + Fe2O3 ---> 2Fe + Al2O3
3) 2AgNO3 + ZnCl2 ---> 2AgCl + Zn(NO3)2
4) H2O2 ---> H2 + O2 *Not sure about this one...
5) Zn + 2HCl ---> ZnCl2 + H2
6) H2SO4 + 2NaOH ---> 2H2O + Na2SO4
7) 2Na + H2 ---> 2NaH
8) CH3COOH + Cu ---> CH3COO + CuH2 *Not so sure about this one... depends on # of ions for copper (can be one or two) and it is complex... Sorry, tried my best!

1.) MgBr2 + Cl2 ===> MgCl2 + Br2
2.) 2Al + Fe2O3 ===> Al2O3 + 2Fe
3.) 2AgNO3 + ZnCl2 ===> 2AgCl + Zn(NO3)2
4.) 2H2O2 ===> 2H2O + O2
5.) Zn + 2HCl ===> ZnCl2 + H2
6.) H2SO4 + 2NaOH ===> Na2SO4 + 2H2O
7.) Incomprehensible
8.) 2HC2H2O2 + Cu ===> Cu(C2H3O2)2 + H2
