Question

2). Balance the following reactions. Use the solubility table to determine what will be the solid product that precipitates, and indicate this with the appropriate phase. _CaCl2 + _AgNO3 → _AgCl + _Ca(NO3)2 _Mg(OH)2 + _CusO.(H20)3* → _Cu(OH)2(H20)2* + _MgSO4 + _H20 _Al2(SO4)3 + _BaCl2 → _Basoa + _AlCl3 These are hydrated coordinated compounds. There is no difference in the reaction, but the water molecules must be balanced. Relative solubilities can be determined based on the non-hydrated form.

Answer 1

first write the all elements in the reaction and then balance them by using smallest possible coefficients and the predict precipitate based on solubility rules as follows
