2. Substances A, B, and C can all act as oxidizing agents. In solution, A is green, B is yellow and C is red. The anions are all colorless. When a solution of A is mixed with B', the color changes from green to yellow, when A is mixed with C the color remains green. Arrange A, B, and C in order of oxidizing strength and explain your answer.

Choose all of the statements from below which are true about oxidation and reduction. Ooxidation and reduction are opposite processes with respect to bookkeeping electrons. O Oxidation is what happens when an element in a substance increases its oxidation number. Electrons appear on the right side of an oxidation half reaction. An oxidant is an oxidizing agent, which becomes reduced during the course of a redox reaction. O Reduction is what happens when an element in a substance decreases its oxidation number. Electrons appear on the left side of a reduction half reaction. A reductant is an reducing agent, which becomes oxidized during the course of a redox reaction. K

1. Balance the following equation using the half-reaction method discussed in experiments 7 and 8. Pay careful attention the condition of the reaction. b. Which element is reduced? SHOW the change in electrons. [ɔisval ON +(HO)nɔ + _ON +nɔ Which element is oxidized? SHOW the change in electrons.

Specify which of the following are oxidation-reduction reactions, and if it is, identify the oxidizing agent, the reducing agent, the substance being oxidized, and the substance being reduced. If it is not, select No and leave the following boxes blank. Express your answers as a chemical formulas. Omit states-of-matter.
