This experimental procedure uses compounds from spinach leaves that are exposed to chromatography‚ TLC plate to indicate the different pigments within the spinach extract. ‘Column chromatography in chemistry is a method used to purify individual chemical compounds from mixtures of compounds’ (Wikipedia‚ 2011). This method is similar to thin layer chromatography‚ but the compounds in the mixture are collected separately. Green dye is used in this experiment that consists of blue and yellow constituents

Experiment 7: A Study of Chemical Changes: Types of Chemical Reaction INTRODUCTION Chemical changes are results of chemical reactions. All chemical reactions involve a change in substance and a change in energy. They are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products. There are different types of chemical reaction classified into 4 general types‚ namely‚ Synthesis‚ Decomposition

Thomas Newberg Chemical Weapons Convention Historically chemical weapons are rarely seen in combat but when they are they are used to great effect‚ killing thousands and injuring many more. Chemical weapons were first used in combat in May 1915 when the Germans released chlorine gas against the French in the Battle of Ypres. Over the course of WWI new chemical agents were developed including cyanide‚ phosgene and mustard gas. The Geneva Protocol of 1925 condemned chemical weapons but states that

The Sequence of Chemical Reactions Drew Selfridge Dave Allen‚ Lab partner Instructor Yang February 11‚ 1997 INTRODUCTION This experiment was to recover the most amount of copper after it is subjected to a sequence of reactions. The copper is originally in solid form‚ but the reactions will turn it into free Cu+2 ions floating in solution. The ions will then be regrouped to form solid copper once again. During this process‚ however‚ some of the Cu+2 ions may be lost. The copper will subjected
