Answer 1

(F) All batteries are rechargeable.

(T) Lithium ion batteries can go up in flames.

(T) Empty batteries are at equilibrium

(T) When using a battery, the reaction goes toward equilibrium

(F) When charging a battery, the reaction goes toward equilibrium

(T) Some batteries need air to function (like Zinc-Air battery)

(T) All batteries have a salt bridge

(F) The voltage to charge a battery is less than the voltage provided during use (because charging voltage is higher)

(T) Batteries turn chemical energy into electrical energy

(T) To get a higher voltage, you can combine multiple electrochemical cells
