		lithium ion
		magnesium ion
		phosphate ion
		lithium and phosphate ions
		nitrate ion
		magnesium and nitrate ions
		phosphate and nitrate ions
		magnesium and nitrate and lithium and phosphate ions
		lithium ion and nitrate ion
		magnesium and lithium ions

Answer 1

The product is highlighted within the rectangle, and the ions are given there.

Molecular equation 3 Mg (NO3)2 (aq) +2 43PO4 (aa) — 62Noz (ag) + mg.3 (PO4)2 (5) Ling is soluble in water Mg (NO3), a Liz POA and and dissociates as a Mg (NO3)2 420 mg 2 + (aq) + 2 Noz caa) Liz POA H2O, 3 Lit can) + POq?- (99) King H2O + (aq) + Nom (as) and will not disso- Mg, (POA), is insoluble in water ciate. 2 . Sonic equation : 3 mg 2+ (aq) + 6 NO2 eaq) + 6 lit (as) + 2 P03 can) [oliteaq) + 6 NOz (aq) + Mg₂ (PO2

So, ions in final solution is : lithium ion and nitrate ion.
