Answer 1

Here is the Solution:

o The net ionic equation for the reaction of ammonium bromide (NH4Br) with barium hydroxide (Ba(OH)2). The ammonium bromide is a Weak acid and barium hydroxide is a Strong base. (1).write the complete balanced chemical equation. + NH4 Br(aq) + Ba(OH)2(aq) →BaBr2(aq) + NH3(g) +H200) 2NH4Br(aq) + Ba(OH)2(aq) +BaBr2(aq) + 2NH3(g) + 2H,00) (ii). Now write the total ionic equation. 2NH4+ (aq) + 2Br (aq) + Ba + (aq) +20H(aq) →Ba- (aq) + 2Br (aq) + 2NH3(g) + 2H200 Now, cancel out the spectator ions on both side of the total ionic equation and write the remaining equation as net ionic equation. 2NH4+ (aq) + 2Br (aq) +Ba2+ (aq) + 2OH(aq) +Bazaq) + 2Br (aq) + 2NH3(g) + 2H200 o The net ionic equation is: NH4+ (aq) + OH(aq) + NH3(g) +H200 o The reaction is classified as: weak acid + strong base
