Sustainable green chemistry
Paint over the metal with paint.
Metal wires/ plate
Molten metal or aqueous solution of ionic compound
Process of passing electricity to bring chemical changes
electrode connected to the positive terminal of the battery
Electrode connected to the negative terminal of the battery
It uses a less/more reactive metal to paint over the metal. So when the protective metal reacts with oxygen and water, it sacrifies itself to protect the metal on the inside.
It is used to speed up a chemical reaction without itself being consumed.

Types of reactions
Reduction is a gain of electrons.
Oxidation is a loss of electrons.
Heat of Combustion
Reaction that absorbs energy.
Reaction that release energy and heat.
Redox reaction is when oxidation and reduction happens simultaneously.
