(a)

Interpretation Introduction

Interpretation: The given each reaction as an oxidation half-reaction or reduction half-reaction has to be explained.

Concept introduction:

The cell reaction can be represented as two half-reactions with the number of transferred electrons. They are as follows:

  • • Oxidation half-reaction.
  • • Reduction half-reaction.

Oxidation half-reaction: The oxidation half-reaction is the part of a redox reaction that shows only for the oxidized species with the transferred electrons and its oxidation state increases with the loss of electrons.

Reduction half-reaction: The reduction half-reaction is also the part of a redox reaction (the counter part of oxidation half-reaction) that shows only for the reduced species with the transferred electrons and its oxidation state decreases with the gain of electrons.

Oxidation: Losing electrons, increasing oxidation number.

Reduction: Gaining electron, decreasing oxidation number.

Hello! I need help calculating the equilibrium constant for the redox reaction Sn(solid) + Zn2+(aqueous) ⇌ Sn2+(aqueous) + Zn(solid) Sn2+ ⇌ + 2e−   Sn(solid) E° =−0.141 V   Zn2+ ⇌ + 2e−   Zn(solid) E° =−0.762 V   My professor said the answer should be about 1.2 x 10-21, but I'm unsure how he came up with that value
Practice Exercise 1If you complete and balance the following oxidation–reduction reaction in basic solutionNO2-(aq)+ Al(s)---->NH3(aq) + Al(OH)4-(aq)   how many hydroxide ions are there in the balanced equation(for the reaction balanced with the smallest whole-numbercoefficients)?(a) One on the reactant side (b) One on the product side(c) Four on the reactant side (d) Seven on the product side(e) None
Procedure: Mix 0.01M KMNO4 and 2 drops of 6M H2SO4 with several drops of 1.0M K2C2O4. Observation: A slight color peach begins to appear.   5K2C2O4(aq) + 2KMnO4(aq)+ 8H2SO4(aq) → 2MnSO4(aq) + 10CO2(aq) + 6K2SO4(aq) + 8H2O(l)   Has oxidation and reduction occurred? If oxidation and reduction has occurred? If oxidation and reduction has occurred define the change in oxidation numbers for the following atoms and define what is undergoing oxidation and reduction:   Mn[ ? ] → Mn[ ? ]   C[ ? ] → C[ ? ]
