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.

it is B complex with vitamin C and iron.the B6and B12 are very important for body for nervous system and circulatory system.Off course iron gets absorbed by the body only Ianthe presence of vit B.

a) Ag2S\nb) SnCl4\nc) Na3N\nd) SrI2\n\nDo us a favor and pay attention during class. That way you'd know how to do these.

NaHCO3 --> Na+ + HCO3-\nCa(NO3)2 --> Ca(2+) + 2NO3-\nAl2(CO3)3 --> 2Al(+3) + 3CO3 (-2)

it's not 1 or 2 because they're nucleotide bases\n\n3 is the only chioce left

1,2-Bis-(2-naphthyl)-2-hydroxy-ethanone (2-Naphthoin)\n\n.................O\n..................||\n(2-naph)-C-CHOH-(2-naph)\n\nwhere (2-naph) represents the 2-naphthyl group [C10H7-]\n\n(ignore the dots in the structure above -- they are used to hold the spaces that Yahoo otherwise deletes)\n\nTotal empirical formula would be: C12H16O2
