For the following balanced equation: 2 Ag+ (aq) + Cu(s) Cu2+ (aq) + 2 Ag(s)
Which letter corresponds to the correct cell notation at standard state conditions?
A. 2Ag+(aq) Cu2+(aq) 2Ag(s) Cu(s)
B. Cu(s) Cu2+(aq) Ag+(aq) Ag(s)
C. Ag+(aq) Cu2+(aq) Cu(s) Ag(s)
D. Cu2+(aq) Cu(s) Ag(s) Ag+(aq)
E. Cu(s) Cu2+(aq) 2Ag+(aq) 2Ag(s)
What reaction is occurring at the anode?
A. Cu Cu2+ + 2e–
B. Cu2+ + 2e– Cu
C. Ag+ + e– Ag
D. Ag Ag+ + e–
I think it's B, A but I'm not sure
Jessie, you have no arrows. How do you know the reactants from the products? Second, the correct answer is not listed for number one. You must space the active phases with a | mark.
Your answers of B and A are correct if you place the arrow and the | at the correct place(s).
I didn't know how to type those in, but I got it. Thanks!
I've seen arrows done three ways.
>> or the reverse of <<.
With the dash and greater than sign as in --> or <--.
I use the equal sign and the greater than sign as in ==> or <== and if I want to show --> and <-- so show equilibrium, I can write it as <--> or <<>> or <==>.
