Question
Specify which of the following are oxidation-reduction reactions, and if it is, identify the oxidizing agent, the reducing agent, the substance being oxidized, and the substance being reduced. If it is not, select No and leave the following boxes blank. Express your answers as a chemical formulas. Omit states-of-matter O La(s) +3Ag+ (aq) 3 Ag(s) + La3+ (aq) Redox? Oxidizing Agent Reducing Agent Substance Oxidized Substance Reduced HI(g) + NH3 (g)-> NH41(s) Redox? Oxidizing Agent Reducing Agent Substance Oxidized Substance ReducedExplanation / Answer
(a) La(s) + 3Ag+(aq) ---> 3Ag(s) + La3+(aq)
Redox - Yes
La - reducing agent. It gets oxidized.
Ag+ - Oxidizing agent. It gets reduced
(b) Redox - No.
(c) Redox - No.
(d) SiBr4(l) + 2Ba(s) ---> 2BaBr2(s) + Si(s)
Redox - Yes
SiBr4 - Oxidizing agent. It gets reduced.
Ba - Reducing agent. It gets oxidized.
(e) Redox - No.
