The equation representing the tarnishing of silver, 2Ag + S 2 − → Ag 2 S + 2 e − is to be classified as oxidation or reduction half-reaction. Concept introduction: The reactions in which one compound undergoes oxidation while the other undergoes reduction are termed as redox reactions. The molecule or compound which loses one or more electrons is said to be oxidized. The molecule or compound which gains one or more electron is said to be reduced.

Choosing reagents and conditions for acetal formation or hydrolysis 0/5 A student proposes the transformation below in one step of an organic synthesis. There may be one or more products missing from the right-hand side, but there are no reagents missing from the left-hand side. There may also be catalysts, small inorganic reagents, and other important reaction conditions missing from the arrow. • Is the student's transformation possible? If not, check the box under the drawing area. If the student's transformation is possible, then complete the reaction by adding any missing products to the right-hand side, and adding required catalysts, inorganic reagents, or other important reaction conditions above and below the arrow. • You do not need to balance the reaction, but be sure every important organic reactant or product is shown. + This transformation can't be done in one step. 5 I H Autumn alo 值 Ar B
