Ba3(PO4)2 ==> 3Ba^2+ + 2PO4^3- Ba(C2H3O2)2 ==> Ba^2+ + 2C2H3O2^- (Ba^2+) = 3x from Ba3(PO4)2 + 0.282 from Ba(C2H3O2) (PO4^3-) = 2x from Ba3(PO4)2 Substitute into Ksp and solve for x = molar solubility Ba3(PO4)2.

This is a limiting reagent problem; I know that because amounts are given for BOTH reactants. 6FeCl2 + 4Na3PO4 → 2Fe3(PO4)2 + 12NaCl mols FeCl2 = grams/molar mass. mols Na3PO4 = grams/molar mass Convert mols FeCl2 to mols Fe3(PO4)2 using the coefficients in the ...

Chemistry Equation(again)
What I wrote is the balanced ionic equation. The ++ are written as exponents and could be written as we usually do it as Cu^+2 + Zn ==> Zn^+2 + Cu. For the molecular equation, it is Cu(NO3)2 + Zn ==> Zn(NO3)2 + Cu So the ionic equation for adding copper(II)...

chem:ionic equations
Jake, you missed it on the products. Nitrates are soluble, but lead phosphate is not. Mg3(PO4)2 + 3Pb(NO3)2 --> 3Mg(NO3)2 (aq) + Pb3(PO4)2 (s) So the net ionic equation is... 2PO4-- + 3Pb++ >> Pb3(PO4)2 (s)

Use the following balanced equation. 3Sr(OH)2 + 2H3PO4 --> 6H20 + Sr3(PO4)2 How many mL of 0.10 M Sr(OH)2 are required to react with 30 mL of 0.30 M H3PO4?

You have given in the problem that the solubility of Pb3(PO4)2 is 2.3E-9. Given that, then concn of Pb MUST be 3 x that (from the ionization equation) and concn PO4^-3 MUST be 2 x that (brom the ionization equation). IF you had 1 Pb ion produced for every 1 molecule of Pb3(PO4...

I've corrected the equation. 2H3PO4 +3Mg(OH)2 ==> Mg3(PO4)2 + 6H20 mols Mg(OH)2 = M x L = ? Convert mols Mg(OH)2 to mols H3PO4 using the coefficients in the balanced equation. Then mols H3PO4 = M H3PO4 x L H3PO4 You know mols and M, solve for L.

No. An equation is balanced only if mass is balanced AND charge is balanced. EQuation (2) balances both. Check the charge changes to verify.
