When lead metal is added to a beaker of hcl(aq), a gas is produced. knowing that lead is oxidized and that hydrogen is reduced, write the balanced net equation for the reaction. (use the lowest possible coefficients. include states-of-matter under the given conditions in your answer.) how many electrons are transferred in the balanced equation? what quantity of useful work can be obtained when pb is added directly to the beaker of hcl?

Two electrons are transferred

Useful work would be 25090 J

Explanation:

When lead metal is added to a beaker of HCl, the lead is oxidized and hydrogen reduced.

Lead will lose two electrons and each atom of hydrogen will accept one electron

The oxidation reaction is:

The reduction reaction is:

Overall equation is:

Useful work is ΔG

ΔG = -nFE°

E° =

E°=0-(-0.13) = 0.13 V

F = 96500 C

n = 2

ΔG = -2X96500X(0.13)= -25090 J

c. orbital shape i hope this is correct
