1) K2CO3 + BaCl2 = BaCO3 + 2KCl 2K(+) + CO3(2-) + Ba(2+) + 2Cl(-) = BaCO3 + 2K(+) + 2Cl(-) Ba(2+) + CO3(2-) = BaCO3; 2) Ca(OH)2 + K2CO3 = CaCO3 + 2KOH Ca(2+) + 2OH(-) + 2K(+) + CO3(2-) = CaCO3 + 2K(+) + 2OH(-) Ca(2+) + CO3(2-) = CaCO3; 3) 3Ba(OH)2 + 2H3PO4 = Ba3(PO4)2 + 6H2O 3Ba(2+) + 6OH(-) + 6H(+) + 2PO4(3-) = 3Ba(2+) + 2PO4(3-) + 6H2O OH(-) + H(+) = H2O; 4) Fe2(SO4)3 + 6KOH = 2Fe(OH)3 + 3K2SO4 2Fe(3+) + 3SO4(2-) + 6K(+) + 6OH(-) = 2Fe(OH)3 + 6K(+) + 3SO4(2-) Fe(3+) + 3OH(-) = Fe(OH)3; 5) K2CO3...
