...oo Verizon o 37% 10:11 PM session.masteringchemistry.com Question I Mastering Chemistry Part A Write the balanced net ionic equation for the reaction that occurs in the following case: Cr2 (SO4)3 (aq) (NH4)2CO3 (aq)- Express your answer as a balanced net ionic equation. Identify all of the phases in your answer. Give Up Submit Part B Identify the spectator ion or ions in this reaction. Express your answer as an ion. If there is more than one answer, separate them by a comma. Submit Give Up Part C Write the balanced net ionic eauation for the reaction that

Explanation / Answer

Cr2(SO4)3 (aq) + 3(NH4)2CO3 (aq) --------------> Cr2(CO3)3(s) + 3(NH4)2SO4(aq)

2Cr+3 (aq) + 3(SO4)2- (aq) + 6(NH4)+ +3CO32- (aq) --------------> 2Cr+3 +3(CO3)2-s) + 6(NH4)++SO4-(aq)

2Cr+3 (aq) +3CO32- (aq) --------------> Cr2(CO3)3(s) net ionic equation

spectator ions NH4^+ , SO4^2-

Ba(NO3)2 (aq) + K2SO4(aq) -------------> BaSO4(s) + 2KNO3(aq)

Ba+2 (aq) +2(NO3)- (aq) + 2K+ (aq) +SO42-(aq) -------------> BaSO4(s) + 2K+(aq) +2NO3-(aq)

Ba+2 (aq) +SO42-(aq) -------------> BaSO4(s) net ionic equation

spectator ions K+ , NO3-

Fe(NO3)2(aq) + 2KOH(aq) -------------> Fe(OH)2 (s) + 2KNO3(aq)

Fe+2(aq)+(NO3)-(aq) + 2K+(aq)+2OH-(aq) -------------> Fe(OH)2 (s) + 2K+ (aq)+2NO3-(aq)

Fe+2(aq)+2OH-(aq) -------------> Fe(OH)2 (s) net ionic equation

spectator ions K+ , NO3^-1
