True or False. Write true if the statement is correct and if false, underline the wrong word or phrase and write the correct word to make the statement true. _______1. The standard cell potential is positive, so the reaction is spontaneous as written. _______2. The electrode in the left half-cell is the cathode because oxidation occurs here. The name refers to the flow of anions in the salt bridge toward it. _______3. A reversible chemical reaction in which one reaction is an redox and the reverse is a reduction.

_______3. A reversible
_______4. A conductor must exist for electrons to be transferred. This conductor is usually some kind of wire so that electrons can move from one site to another.
_______5. The silver half-cell reaction must be multiplied by three.
_______6. Reduction occurs at the anode.
_______7. The silver half-cell will undergo reduction because its standard reduction potential is higher.
_______8. When the
spontaneous reaction and that the electrons are flowing from the left to the right.
_______9. The copper is undergoing oxidation; therefore, the copper electrode is the cathode.
_______10. Electricity is used to plate objects with decorative metals like gold or chromium.
