Answer 1

From the stoichiometry, the reaction will be
3Tl\(^+\) +2 VO\(_3^-\)

If Tl goes from +1 to +3 that's an increase of 2.

So V must undergo a decrease of 3, in order to balance the oxidation numbers.

In VO\(_3^-\), V is +5, so it will become: 5 - 3 = +2 in the end.

Answer 2

Thanks :)

Answer 3

number of moles of Tl+NO3-=10*0.30/1000
=3*10^-3
Number of moles of NH4+VO3-=20*0.10/1000
=2*10-3
Divide by the smalles figure, we would obtain the ratio of 1.5:1 *2 to get rid of a fraction so the mole ration will 3:2 so for every 3 moles of Tl+( six electrons are removed) only two moles are reduced so divide the six electrons by 2 to figure out how many electrons are gained per mole
