What is the dot diagram for Ca(OH)2?

There's no way I can type a lewis structure lol.

MgO and BaO will react with water to form the hydroxides Mg(OH)2 and Ba(OH)2, those will be neutralized by hydrochloric acid to give the chlorides MgCl2 and BaCl2 and water.  I think you may have gotten C2O wrong, that is not a real chemical compound.  If you meant CaO it will behave in the same way as MgO and BaO.

8 dots around each element. this is a salt, so is realtively stable. hope that helps!

Ca goes from an oxidation state of zero to an oxidation state of +2.  This indicates that Ca lost electrons and is therefore oxidized in this equation.  Also Oxygen in O2 has an oxidation state of zero and goes to an oxidation state of -2 in the CaO.  Since Oxygen gained electrons it was reduced in the reaction.

Found a good diagram here\nhttp://www.laynetworks.com/Block%20diagram%20of%20the%20Pentium.htm

c since calcium carbonate  = CaCO3 and they react to produce calcium nitrate(Ca(NO3)2), carbon dioxide(CO2) and water(H2O).

1. \nMoles of Ca(HCO3)2 produced = 3.05 x 10^10/Molecular Mass of Ca(HCO3)2\n=3.05 x 10^10/162\n=0.018 x 10^10\n\nFrom the equation we know on dissolving 1 mole of limestone we get 1 mole of Ca(HCO3)2 \nThus, if 0.018 x 10^10 moles of Ca(HCO3)2 are produced moles of limestone dissovled should be 0.018 x 10^10\nWeight of limestone dissolved = Moles x its Molecular Mass of limestone\n=(0.018 x 10^10) x(100)\n=1.8 x 10^10 gm.\n\n2.\na.) CO + 2H2 --> CH3OH\n\nb.)Moles of methanol to be produced = 45/Molecular Mass of CH3OH\n=45/32\n=1.40625\n\nFrom the equation we know 2 moles of H2 are required to produced 1 mole of methanol\nThus to produce 1.40625 moles of H2 required = 2*1.40625\nWeight of H2 required = Moles X Molecular mass of H2\n=(2 x 1.40625) x 2\n=5.625 gm

Ca(OCl)2 as far as i rem being taught in chemistry....U should have paid attention in ur class.....

You need to make sure that there is the same number and kind of atoms on each side of the arrow.\n\nCa(OH)2 + MgCl2 ---> Mg(OH)2 + CaCl2, both Mg and Ca stay+2\n\nBaO2(s) + H2SO4 ---> BaSO4(s) +H2O2 \n\nAg2S --->2 Ag+  +  S-2\n\nHC2H3O2 + MgCO3 (s) ---> H2O + CO2 + Mg+C2H302-\n\nI 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.
