If We Had Known About Green Chemistry In 1951‚ How Would Things Be Different Today? Green Chemistry is the making of chemical products that reduces or eliminates the use and production of hazardous substances in the designing‚ making‚ and use of chemical products. It involves the designing and re-designing of chemical creation and chemical products to prevent pollution which will therefore solve environmental problems. Green Chemistry is environmentally safe and has very little side effects on

The Chemistry of Lipids Experiment #8 Objective To observe the solubility of lipids in polar and nonpolar solvents and to compare saturated and unsaturated fats in their chemical reaction with bromine. The percent fat in a food will be determined by extraction of the fat and weighing it. Introduction Lipids‚ by definition‚ are natural substances that do not mix with water but dissolve in organic solvents. There are several classes of lipids‚ including: fatty acids‚ waxes‚ triacylglycerols
