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. b) What volume of 16M HNO3 solution provides the required amount of the acid?
