(Solved): Hello can someone help me for these questions from a to d as soon as possible tnx  On the basis ...

On the basis of the general solubility rules, choose a balanced molecular equation for the precipitation reactions that take place when the following aqueous solutions are mixed. General Rules for Solubility of Ionic Compounds (Salts) in Water at 25 °C. 1. Most nitrate (NO) salts are soluble. 2. Most salts of Na, K, and NEL are soluble. 3. Most chloride salts are soluble. Notable exceptions are AgCl, PbCl, and Hg? Cl?. 4. Most sulfate salts are soluble. Notable exceptions are BaSO4, PbSO4, and CaSO4. 5. Most hydroxide compounds are only slightly soluble. The important exceptions are NaOH and KOH. Ba(OH)2 and Ca(OH), are only moderately soluble. 6. Most sulfide (8²), carbonate (CO?), and phosphate (PO) salts are only slightly soluble." *The terms insoluble and slightly soluble really mean the same thing: such a tiny amount dissolves that it is not possible to detect it with the naked eye. a. Iron(III) chloride, FeCls, and sulfuric acid, H?SO4 O Rule 4: an exception to the rule for sulfates; 2FeCl, (aq) + 3H?SO4 (aq) ? Fe?(SO4)3(aq) + 6HCl(aq) O Rule 4: an exception to the rule for sulfates; 2FeCls (aq) + 3H?SO4 (aq) ? Fe?(SO4)3 (8) + 6HCl(aq) There is no precipitate: both Fe2(SO4)3 and HCl are soluble; FeCl, (aq) + H?SO4 (aq) ? no precipitate Rule 4: an exception to the rule for sulfates; FeCls (aq) + H?SO, (ag) ? Fes (SO.)s(s) + HCl(aq) - b. Potassium carbonate, K?CO3, and calcium chloride, CaCl? Rule 6: Most carbonate salts are only slightly soluble: K?CO, (aq) +CaCl? (aq) ? CaCO, (a) + KCl(aq) Rule 6: exeption to rule for carbonates; 2K.CO (ao) +CaCl(aq) ? CaCOx(s) +2KCl(aq)
