Question

Given the particulate model for a chemical reaction, answer the following questions. The other ions in solution are nitrate (negatively charged ion) and hydronium (positively charged ion).

10 Question (2 points) a See page 330 Given the particulate model for a chemical reaction, answer the following questions. The other ions in solution are nitrate (negatively charged ion) and hydronium (positively charged ion). 1st attempt Part 1 (1 point) See Periodic Table O See Hint Write the chemical formula for the spectator ions. If there are no spectator ions, leave the boxes empty. and Part 2 (1 point) O See Hint Write the balanced net ionicequation for the reaction that occurs. If no reaction occurs, write no rxnin the first box. Please include states of matter for each component in the reaction.

Explanation / Answer

Bromine ions are negatively charged and attracts towards the Hydronium ions and form Hydrogen bromide.

H+(aq) + Br-(aq) = HBr(aq)

Lead ions are positively charged and attracts towards the nitrate ions and form Lead nitrate.

Pb2+(aq) + 2NO3-(aq) = Pb(NO3)2(aq)

Part a

Spectator ions are nitrate ions and Hydronium ions

NO3- and H+

Part b

Molecular balanced reaction

Pb(NO3)2(aq) + 2 HBr(aq) = 2 HNO3(aq) + PbBr2(s)

Lead nitrate + Hydrogen bromide = nitric acid + lead bromide

Molecular ionic equation

Pb2+(aq) + 2(NO3)-(aq) + 2H+(aq) + 2Br-(aq) = 2H+(aq) + 2NO3-(aq) + PbBr2(s)

Net ionic equation

Pb2+(aq) + 2Br-(aq) = PbBr2(s)
