(a) Interpretation: The amount of zinc that formed should be calculated when 3.35 × 10 − 2 g of Ni(OH) 2 are consumed by the nickel-zinc battery. Concept introduction: The amount of substance produced at an electrode by electrolysis depends on the quantity of charge passed through the cell. The number of moles of electrons that go through the cell is responsible for the amount of mass or else moles that producing at the cathode or anode. Charge(C)= Current(A)×Time(s)

Definition Definition Number that is expressed before molecules, ions, and atoms such that it balances out the number of components present on either section of the equation in a chemical reaction. Stoichiometric coefficients can be a fraction or a whole number and are useful in determining the mole ratio among the reactants and products. In any equalized chemical equation, the number of components on either side of the equation will be the same.
