Question 61

Multiple Choice

Which balanced chemical equation could represent the following result of a precipitation reaction? Which balanced chemical equation could represent the following result of a precipitation reaction? A) 2K<sub>3</sub>PO<sub>4</sub>(aq) + 3Cr<sub>2</sub>(SO<sub>4</sub>) <sub>3</sub>(aq) → CrPO<sub>4</sub>(s) + 6KCl(aq) B) MgSO<sub>4</sub>(aq) + 2AgNO<sub>3</sub>(aq) → Ag<sub>2</sub>SO<sub>4</sub>(s) + Mg(NO<sub>3</sub>) <sub>2</sub>(aq) C) MgCl<sub>2</sub>(aq) + 2AgC<sub>2</sub>H<sub>3</sub>O<sub>2</sub>(aq) → 2AgCl(s) + Mg(C<sub>2</sub>H<sub>3</sub>O<sub>2</sub>) <sub>2</sub>(aq) D) K<sub>2</sub>CrO<sub>4</sub>(aq) + 2AgNO<sub>3</sub>(aq) → Ag<sub>2</sub>CrO<sub>4</sub>(s) + 2KNO<sub>3</sub>(aq) E) K<sub>2</sub>S(aq) + Pb(NO<sub>3</sub>) <sub>2</sub>(aq) → PbS(s) + 2KNO<sub>3</sub>(aq)


A) 2K3PO4(aq) + 3Cr2(SO4) 3(aq) → CrPO4(s) + 6KCl(aq)
B) MgSO4(aq) + 2AgNO3(aq) → Ag2SO4(s) + Mg(NO3) 2(aq)
C) MgCl2(aq) + 2AgC2H3O2(aq) → 2AgCl(s) + Mg(C2H3O2) 2(aq)
D) K2CrO4(aq) + 2AgNO3(aq) → Ag2CrO4(s) + 2KNO3(aq)
E) K2S(aq) + Pb(NO3) 2(aq) → PbS(s) + 2KNO3(aq)
