TRUE OR FALSE 1. Free metals have oxidation numbers the according to their group number in the periodic table of elements. 2. The lithium ion battery has more energy per unit mass than nickel-cadmium batteries.
Science behind corrosion-test
Corrosion is defined as an activity that transforms refined metals into more chemically stable forms such as oxide, hydroxide, carbonate, or sulfide. It refers to the slow decomposition of things (typically metals); thanks to chemical and/or electrochemical reactions with their surroundings. Corrosion engineering is the science of preventing and controlling corrosion.
