Unformatted text preview: Use the following table of standard reduction potentials to assist in answering the questions. Li + Li-3.0V Na+ Na-2.7V Al +3 Al-1.7V Zn +2 Zn-0.7V Fe +3 Fe-0.1V H + H 2 0.0V Cu +2 Cu 0.3V NO 3- NO 1.0V Cl 2 2Cl- 1.4V MnO 4- Mn +2 1.5V Au + Au 1.7V F 2 2 F- 2.9V 1. Consider the formation of copper fluoride. Using the half cell reactions written above, what is the final reaction? a. copper ion is oxidized and fluorine gas is reduced b. copper ion is reduced and fluorine ion is oxidized c. copper ion is reduced and fluorine gas is reduced d. copper is oxidized and fluorine gas is reduced e. copper is reduced and fluorine gas is oxidized To form copper fluoride, CuF2, copper has to lose electrons to become the copper ion, an oxidation. Fluorine gas has to gain electrons to become fluorine ion, a reduction. 2. What is the sum of the coefficients when the following reaction is balanced in base?...
