Write a balanced overall reaction from these unbalanced half-reactions sn and ag

Chemistry

Balance each one by adding electrons to make the charges on both sides the same:

Sn--> Sn2+ + 2 e-
Ag+ + 1 e- --> Ag

Now, you have to have the same number of electrons in the two half-reactions, so multiply the second one by 2 to get:

2 Ag+ + 2 e- --> 2 Ag

Now, just add the two half reactions together, cancelling anything that's the same on both sides:

2 Ag+ + Sn --> Sn2+ + 2 Ag

And you're done.

If you use 19 mL of 0.100 M KMnO4, how many moles have you used? The answer has to be in four decimal places (do not forget the
Scorpion4ik [409]
1)

Volume = 19 / 1000 = 0.019 L

n = M * V

n = 0.100 * 0.019

n = 0.0019 moles
__________________________

2)

 M₁ * V₁ = M₂* V₂

5.0 * V₁ = 1.0 * 152

5.0 V₁ = 152

V₁ = 152 / 5.0

V₁ = 30.4 mL
