Which of the following compounds has the lowest van't Hoff factor? What is the van't Hoff factor of NaNO3, Na3PO4, Li2CO3, MgCl2? I calculated them all to be (in order) a van't Hoff factor of 4, 7, 5, and 3. However the lowest van't Hoff factor went to NaNO3. Why?
Which of the following will occur when solutions of ZnSO4(aq) and MgCl2(aq) are mixed? A precipitate of MgSO4 will form; Zn and CI" will be spectator ions. A precipitate of ZnCl2 will form; Mg and SO4 will be spectator ions. O No precipitate will form. A precipitate of MgCl2 will form: Zn2 and SO4will be spectator ions. A precipitate of ZnSO4 will form ; Mg" and CIT will be spectator ions.
Consider the following reaction. MgCl2(aq)+2NaOH(aq)⟶Mg(OH)2(s)+2NaCl(aq) A 166.0 mL solution of 0.381 M MgCl2 reacts with a 47.33 mL solution of 0.568 M NaOH to produce Mg(OH)2 and NaCl. Identify the limiting reactant. NaOH Mg(OH)2 MgCl2 NaCl Caclulate the mass of Mg(OH)2 that can be produced. The actual mass of Mg(OH)2 isolated was 0.559 g. Calculate the percent yield of Mg(OH)2.
Why would adding MgCl2 aliquots to a saturated Mg(OH)2 solution change the pH? a. because MgCl2 is a strong base O b.because MgCl2 is not water soluble OC. because MgCl2 is a strong acid O d. because of the common ion effect
