Homework Statement
3Ag2 S + 2Al --> 6Ag + Al2 S3
consider the equation for silver tarnishing.
a) state the oxidation number for each element in the reaction.
b)identify the the oxidized reactant and the reduced reactant.
The Attempt at a Solution
Ag2=2 S= -2 Al=0 ---> Ag=-2 Al2=0 S=2
Ag2 loses the electron so it is the oxidized reactant.
S gains the electron so it is the reduced reactant.
am i close to having the right answer?
