Answer 1

yes .precipitate of Mg3(PO4)2 forms
Net ionic equation
3Mg2+(aq) + 2PO43- (aq) --> Mg3(PO4)2 (s)
************

Ca2+, Ag+

yes/no	reagent	precipitate
yes	KBr	AgBr
no	K2S	Ag2S,CaS both forms precipitate
yes	Na2SO4	Ag2S

d) Ca2+ and Fe2+

ye/no	reagent	precipitate
No	NaBr
No	K2CO3	FeCO3,CaCO3 both forms precipitate
No	K2SO4
