A battery is constructed based on the oxidation of magnesium and the reduction of Cu2+. The initial concentrations of Mg2+ and Cu2+ are 1.1×10⁻⁴ M and 1.6 M , respectively, in 1.0-liter half-cells. What is the initial voltage of the battery? Answer:2.8. What is the voltage of the battery after delivering 5.0 A for 8.0 h ? How long can the battery deliver 5.0 A before going dead? Please show all step thank you

Redox (oxidation-reduction) reactions in glycolysis

Part A - Redox (oxidation-reduction) reactions in glycolysis In glycolysis, as in all the stages of cellular respiration, the transfer of electrons from electron donors to electron acceptors plays a critical role in the overall conversion of the energy in foods to energy in ATP. These reactions involving electron transfers are known as oxidation-reduction, or redox, reactions. Drag the words on the left to the appropriate blanks on the right to complete the sentences. 1.
