Chemistry reactions.?
First i want to say Happy Thanksgiving to everyone!!!
Ok, so i have these reactions i did on a quiz yesterday, and i dont know if i did it right.
are these correct? ((Written in net ionic form))
1. Calcium Hydroxide and Magnesium Chloride
Ca(OH)2+Mg+2-->Ca+2+Mg(OH...
2. Solid Barium Peroxide added to Sulfuric Acid
BaO2(s)+H2SO4--->BaSO4(s)...
3. Silver sulfide and nitric acid
Ag2S-->Ag+ + S-2
4. Acetic Acid and Magnesium Carbonate
HC2H3O2+MgCO3(s)-->H2O + CO2+Mg+2 +C2H3O2-1
are any of these correct??
THANK you in advance and have a very nice and wonderful THANKSGIVING!! :)

Sorry these ones got cut off, here are the complete.
1. Calcium Hydroxide and Magnesium Chloride
Ca(OH)2+Mg+2-->Ca+2+Mg(OH)2(s)
2. Solid Barium Peroxide added to Sulfuric Acid
BaO2(s)+H2SO4--->BaSO4(s)+H2O2

oh, yea i know how to balance them. my teacher said we didnt have to balance them. thanks!

You need to make sure that there is the same number and kind of atoms on each side of the arrow.
Ca(OH)2 + MgCl2 ---> Mg(OH)2 + CaCl2, both Mg and Ca stay+2
BaO2(s) + H2SO4 ---> BaSO4(s) +H2O2
Ag2S --->2 Ag+ + S-2
HC2H3O2 + MgCO3 (s) ---> H2O + CO2 + Mg+C2H302-
I may not have written net ionic form, but I did get all the atoms on each side I am unsure of the reaction producing hydrogen peroxide, but you do have to account for all atoms.

For starters, calcium hydroxide and sulfuric acid dissociate in aqueous solutions, so alas 1 & 2 are incorrect.
4 looks good. acetic acid does not dissociate in water, and MgCO3 does reaact in that matter. I don't know about 3.
