These are the right ones:\n\n2K(s) + 2H2O(l) ---> 2KOH(aq) + H2(g)\nH2SO4(aq) + 2KOH(aq) ---> K2SO4(aq) + 2H2O(l)\nCa(OH)2(aq) + 2HCl(aq) ---> CaCl2(aq) + 2H2O(l)

Ba(NO3)2 + Na2CO3-->BaCO3 +2NaNO3\n\nto do a double displacement follow this formula\n\nAB + CD --> AD + CB

Na2EDTA is a complex molecule. Its name stands for ethylenediaminetetraacetic acid – disodium salt. The formula is Na2C10H14N2O8. Even though its name and structure are complex, you only need to know that: EDTA reacts with Ca+2 and Mg+2 in a one to one ratio as follows:\n:Ca+2 + EDTA-2 -----> CaEDTA\n\nMg+2 + EDTA-2 -----> MgEDTA\nThe formula mass of Na2EDTA dihydrate is 372.24 g/mole.Na2EDTA comes as a dihydrate(absorbs water from the atmosphere) which is efflorescent (literally means "bursting into flower" but in this case just means that it forms bubbles), you cannot reliably weigh out the desired number of grams. The salt may be fully, or only partially, hydrated at the time you weigh it. The result is that you cannot be certain that you have prepared the proper strength reagent of EDTA..therefore: you need to standardize the solution  The results of the titration is reported as mg of CaCO3/liter.\nTo convert Calcium plus Magnesium (meq/L) Hardness as CaCO3 (mg/L) 50\nOf course since Fe and Mg and Ca and other metals are also present in water it is better (more accurate) to titrate for each metal species individually and calculate the hardness using the results of the individual results. EDTA hardness is sometimes referred to as "Total hardness"and is reported as " Hardness as mg/l CaCO3."

The formula would be Al2(CO3)3; the numbers are subscripts. \n\nLearn your charges for the polyatomic ions and for the other elements, it will really help.

I assume you are talking about ordinary table salt, sodium chloride (NaCl).  \n\nThe molecular mass of NaCl is 58.44 gm/mol.  One gram of NaCl therefore contains:\n\n1 gm / (58.44 gm/mol)= 1.711*10^-2 moles\n\nEach mole of Na is equal to one "equivalent" because Na forms ions that have a charge of +1, so for Na+:\n\n1.711*10^-2 moles = 1.711*10^-2 equivalents = 17.11 milliequivalents

I think you are talking about Aluminum zirconium tetrachlorohydrex gly (used in anti perspirants). the molecular formula is\n\nAlyZr(OH)3y+4-xClxmGlynH2O

Calcium chloride = CaCl2 = Mwt 110.98\n% Ca = (40.08 / 110.98)*100 = 36.11%\n% Cl = (70.90 / 110.98)*100 = 63.89%\n\nCalcium chloride dihydrate = CaCl2.2H2O = Mwt = 147.01\n% Ca = (40.08 / 147.01)*100 = 27.26%\n% Cl = (70.90 / 147.01)*100 = 72.74%\n\nOther hydrates can be calculated in the same way.\n\nHope this helps.
