Question

A voltaic cell with an alkaline (basic) aqueous electrolyte is based on the reaction between MnO₄^–(aq) and Cd(s), producing MnO₂(s) and Cd²⁺(aq). Write a half-reaction for the cathode. Please include the states of matter in the equations.

Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
