Front 7

Energy cannot be created or destroyed but can be transferred from one to another

Back 7

Law of conservation of energy.

Front 8

have a sour taste and tend to react with metals. they are corrosive and will break about the bonds with metal compounds many times releasing hydrogen gas. They will conduct electric current

Acids

Front 9

Have a bitter taste and a slippery feel to them. They will conduct electric current and are found in many household products.
