Potential energy is stored energy and the energy of position. Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy.
What are the common sources of chlorine?
Halite (sodium chloride or ‘common salt’) is the main mineral that is mined for chlorine. Sodium chloride is a very soluble salt that has been leached into the oceans over the lifetime of the Earth. Several salt beds, or ‘lakes’ are found where ancient seas have evaporated, and these can be mined for chloride.
What are chemical contaminants food handlers?
Examples of Chemical Contamination Common examples of artificial chemical contaminants include detergent, sanitizer, other cleaning products, fertilizers, herbicides, and pesticides.
