Answer 1

part-A

2HBr(aq)+Ca(OH)2(aq)?2H2O(l)+CaBr2(aq)

part-B

2H^+ (aq) +2Br^-(aq)+Ca^2+ (aq) +2(OH)^-(aq)?2H2O(l)+Ca^2+(aq) +2Br^-(aq)

removal of spectatro ions to get net ionic equation

2H^+ (aq) +2(OH)^-(aq)?2H2O(l) net ionic equation

part-C

Cu(OH)2(s)+2HClO4(aq)?Cu(ClO4)2(aq) + 2H2O(l)

part-D

Cu(OH)2(s)+2H^+ (aq) +2ClO4^-(aq)?Cu^2+(aq)+2(ClO4)^-(aq) + 2H2O(l)

removal of spectator ions to get net ionic equation

Cu(OH)2(s)+2H^+ (aq) ?Cu^2+(aq)+ 2H2O(l)   net ionic equation

part-E

Al(OH)3(s)+3HNO3(aq)?Al(NO3)3(aq) + 3H2O(l)

part-F

Al(OH)3(s)+3H^+ (aq) +3NO3^-(aq)?Al^3+(aq) +3(NO3)^-(aq) + 3H2O(l)

removal of spectator ions to get net ionic equation

Al(OH)3(s)+3H^+ (aq) ?Al^3+(aq) + 3H2O(l) net ionic equation
