21. Consider the following balanced chemical reaction between a metal "M" in its elemental form (uncombined state), and oxygen gas (O,) to produce a metal oxide with a formula M,0: 4M(5) + Ozig) → 2M20[s) Use the space below to work out how many electrons are either lost or gained by each of the reactants. For full credit, make sure to clearly show the oxidation numbers of each atom and the number of electrons involved in the transfer.

27) The cycle of copper reactions illustrates important principles of chemical reactions. The cycle begins with elemental copper, which in a first reaction is oxidized to copper(II) cation. Copper(II) is then carried through different solid forms. In the last step, copper(II) cation is reduced, the copper metal is regenerated, and the cycle is closed. The five key steps are (see attached picture). Assume that you want to carry out a sequence of cycle reactions. d) What volume of 3.0M NaOH solution provides the required amount of the base?

A solution of iron(II) sulfate was prepared by dissolving 10.00 g of FeSO4•7H2O (FW = 277.9) in water and diluting up to a total volume of 250 mL. The solution was left to stand, exposed to air, and some of the iron(II) ions became oxidized to ron(III) ions. A 25.0 mL sample of this partially oxidized solution required 23.70 mL of 0.0100 M potassium dichromate K2Cr2O7 solution for complete reaction in the presence of dilute sulfuric acid. Calculate the percentage of iron(II) ions that had been oxidized by the air.
