Question

Complete and balance each of the following equations. If no reaction occurs, enter NOREACTION.

Part A

Ca(NO3)2(aq)+KCl(aq)→

Express your answer as a chemical equation. Enter NOREACTION if no reaction occurs. Identify all of the phases in your answer.

Part B

NaCl(aq)+Mg(C2H3O2)2(aq)→

Express your answer as a chemical equation. Enter NOREACTION if no reaction occurs. Identify all of the phases in your answer.

Part C

(NH4)2SO4(aq)+CuCl2(aq)→

Express your answer as a chemical equation. Enter NOREACTION if no reaction occurs. Identify all of the phases in your answer.

Part D

Al2(SO4)3(aq)+AgNO3(aq)→

Express your answer as a chemical equation. Enter NOREACTION if no reaction occurs. Identify all of the phases in your answer.

Answer 1

A) Ca(NO3)2 + KCl(aq) ------------> no reaction

As all the ions are spectator ions , no precipitation or gas evolution occurs.

B)NaCl(aq) + Mg(C2H3COO)2 (aq) ------------> no reaction

Here also all the ions remain spectator , no net reaction.

C) (NH4)2SO4 (aq) + CuCl2(aq) --------------> no reaction

all the ions remain in solution, no precipitation or no gas formation

D) Al2(SO4)3 (aq) + 3AgNO3(aq) --------------> 3AgSO4 (s) + 2Al(NO3)3 (aq)

As silver sulphate is insoluble in water it is precipitated Al+3 and NO3- remain in solution as spectator ions
