Chemistry of Fireworks By Anuradha Sahu Everyone enjoys the amazing firework shows on the Fourth of July with the beautiful vibrant colors and sparks every year. Fireworks have been part of this world for a very long time. They have been used for enjoyment and for signalling purposes. Every culture has their own significance and use of fireworks. But all fireworks have something in common; the chemistry that makes them work. No matter where you find them‚ they are made up of the same compounds

A. Role of Chemistry in Society Applications of chemical science have contributed significantly to the advancement of human civilization (1‚ 2‚ 3). With a growing understanding and ability to manipulate chemical molecules‚ the post-World War II chemist was considered a societal problem solver. They synthesized crop-enhancing agricultural chemicals to ensure a constant and viable food supply. They played a significant role in the eradication of deadly diseases by developing life-saving pharmaceuticals

The Chemistry of Toothpaste Toothpaste is not a new thing. It has been traced back to Ancient Egypt. They used a powdered rock and vinegar‚ which created a chemical reaction that dissolves the plaque on teeth. In 1900’s people used hydrogen peroxide and baking soda or chalk‚ pulverised brisk and salt as a toothpaste. Toothpastes today‚ are mostly made up of abrasives‚ surfactants‚ a detergent‚ a thickener‚ a moisturizer‚ water‚ flavouring agents‚ coloring‚ sweeteners‚ fluoride and desensitizers

EXPERIMENT 3 DETERMINATION OF ORGANIC MATTER BY WALKEY- BLACK WET OXIDATION METHOD OBJECTIVE: This method determines the percentage of organic carbon and organic matter in the soil. INTRODUCTION The soil sample is suspended in standard potassium dichromate (K2Cr2O7) solution to which concentrated sulphuric acid is then added. The heat generated on adding the sulphuric acid and the presence of chromic acid creates strong oxidizing conditions. The excess chromic

CLASSIFICATION TESTS FOR ORGANIC HALIDES James Anand L. Regala‚ Sabrina Nicolle G. Sarte‚ Ann Michelle Siao‚ Michael Sibulo‚ Victoria Tan Group 8 2C Pharmacy Organic Chemistry Laboratory ABSTRACT This experiment is done to classify organic halides. Most organic halides are synthetic and are not flammable. One way to classify organic halides is by classifying its -carbon atom as primary‚ secondary or tertiary. If the -carbon is attached to one R group‚ it is then primary. If the -carbon is
