help with any of these questions would be greatly appreciated!!

Use the following redox reaction to answer all of the questions:
Sn2+(aq)+Al(s)—>Sn(s)+Al3+(aq)
1. Balance the reaction
2. What is the reduction half in the above reaction?
3. What is the oxidation half?
4. Could the reaction be used to create a galvanic cell as written? If so, what reaction would occur at the anode? What reaction would occur at the cathode?
5. Determine the standard cell potential for the galvanic cell.

Has anyone used a Rosemount 2081 as an Oxidation-Reduction Potential transmitter?

I believe it is possible but don’t know how to wire it

If the reduction half-reaction Cd(2+)(aq) + e- ? Cd(s) has to be multiplied by 2 to balance the electrons before you add it to an oxidation half reaction, what is the electrical potential of this reduction half reaction?

I got an answer of -0.40 V. Am i correct?

umm ok so here goes:
using standard electrode potentials, select a halogen that can be released from a halogen acid by dichromate (VI) solution (Cr2O7) 2- and one that cannot. give your reasons and write a balanced equation for the release of the halogen. 5 marks

have absolutely no idea. what are standard electrode potentials? and how do you decide which halogen acid ‘works’ and which doesnt? ANY ideas??

The whole question is “If the standard reduction potential of a half-cell is positive, which redox reaction is spontaneous when paired with a hydrogen electrode?”

the choices are:
A. Oxidation
B. Reduction
C. Both a and b
D. neither a nor b

What are the common reactions, oxidation-reduction potential, crystalline forms, combustability, acid/base properties, and common bond types of silver

We know that looking at the reduction potential table, hydrogen has an EMF of zero at all temperatures and is always highlighted in the table.
What if we take out hydrogen from the table, and create my own standard table, which one would be highlighted?
i really really really really need help, so if you need more info about my question or dont understand what i have said, can you ask me!
THANKSS iin aadvance

i have Absolutely no idea what this means and i need the answer for my chemistry project. does anyone know the answer?

I’ve been stuck on this way longer than I need to be. The choices are:

A.The cell potential is the total voltage for the oxidation and reduction half-reactions, and the standard reduction potential is the voltage of just the reduction half-reaction.
B.Standard reduction potentials are measured at 0 atm while cell potentials can be measured at any pressure.
C.The cell potential is the voltage of the oxidation half reaction, and the standard reduction potential is the voltage of just the reduction half-reaction.
D.Cell potentials can be either positive or negative, but standard reduction potentials are always positive.
E.Standard reduction potentials are measured at 0C while cell potentials can be measured at any temperature.
