Answer:
Depending on the 
value of 
, the cell potential would be:
, using data from this particular question; or- approximately
, using data from the CRC handbooks.
Explanation:
In this galvanic cell, the following two reactions are going on:
- The conversion between
and 
ions, 
, and - The conversion between
and 
ions, 
.
Note that the standard reduction potential of ions to is higher than that of ions to . Alternatively, consider the fact that in the metal activity series, copper is more reactive than silver. Either way, the reaction is this cell will be spontaneous (and will generate a positive EMF) only if ions are reduced while is oxidized.
Therefore:
- The reduction reaction at the cathode will be: . The standard cell potential of this reaction (according to this question) is
. According to the 2012 CRC handbook, that value will be approximately 
.
- The oxidation at the anode will be:
. According to this question, this reaction in the opposite direction () has an electrode potential of 
. When that reaction is inverted, the electrode potential will also be inverted. Therefore, 
.
The cell potential is the sum of the electrode potentials at the cathode and at the anode:
.
Using data from the 1985 and 2012 CRC Handbook:
.
Weast to east , east to west, nort to south, south to nort.
Steel is an alloy and consists of more than one element (mainly iron and carbon), therefore steel is a mixture.
Answer:
When you mix the sugar into the tea and stir, it dissolves so you can't see it. Also when you stir the sugar into the tea the taste changes and it turns sweeter.
