Assuming an efficiency of 36.40% calculate the actual yield of magnesium nitrate formed from 122.6g of magnesium and excess copper(II) nitrate. Mg + Cu(NO3)2 ⟶ Mg(NO3)2 + Cu

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.  a) How many mmol of HNO3​ are required to completely react with 2.51g of copper in the first step of the cycle?
