The table of standard reduction potential of substances lists common metals in order of increasing reduction potential and decreasing oxidation potential. Which metal will most easily corrode?
a ) Li b) A1 c) Cu d) Au

How can you make a non-spontaneous redox reaction take place in a cell?

Why is the electrolyte necessary in both galvanic and electrolytic cells?

What happens to the case of a carbon-zinc dry cell as the cell is used to produce an electric current?

What is the function of the salt bridge in a galvanic cell?

What is the difference between an electrolytic cell and a galvanic cell?

Magnesium from the Sea Magnesium in seawater is found mostly as $\mathrm{Mg}(\mathrm{OH})_2$, which can be converted to $\mathrm{MgCl}_2$ by reacting it with $\mathrm{HCl}$. Magnesium metal can then be purified by electrolysis of molten $\mathrm{MgCl}_2$. a) What reaction takes place at the cathode during electrolysis? b) What reaction takes place at the anode during electrolysis? c) Write an equation for the net reaction that occurs.

Which process is not an application of electrolysis?
a ) electroplating
b) cleaning toxic wastes
c ) separating metals from ores
d) creating synthetic diamonds

Acetylene $(C_2H_2)$ and nitrogen $(N_2)$ both contain a triple bond, but they differ greatly in their chemical properties. Calculate the enthalpy of oxidation per mole for $N_2$ and for $C_2H_2$ (the enthalpy of formation of $N_2O_5(g)$ is 11.30 kJ/mol).

What is the oxidation state of the halogen in each of the following? (a) $\mathrm{H}_5 \mathrm{IO}_6$ (b) $\mathrm{IO}_4^{-}$ (c) $\mathrm{ClO}_2$ (d) $\mathrm{ICl}_3$ (e) $\mathrm{F}_2$

In the below reaction, identify which element is oxidized and which is reduced by assigning oxidation numbers:

$$\text{$\mathrm{Mg}(s)+2 \mathrm{HBr}(a q) \rightarrow \mathrm{MgBr}_2(a q)+\mathrm{H}_2(g)$}$$
