Take Home Test Perchloric acid’s chemical formula is HClO4. This acid is not usually used alone. It is used for a solvent for metals and alloys a dehydrating agent‚ particularly in the determination of silica in iron and steel and in cement and other silicate materials. It is also used as a solvent for sulfide ores for the determination of copper and other metals‚ in the separation and determination of the alkali metals sodium and potassium. In the manufacture of anhydrous magnesium

“The Chemistry of Barbecue and You” is an article that creatively talks about the Maillard reaction. The Maillard reaction is a chemical reaction different foods undergo in order to acquire a distinctive flavor or the brownish color. According to the article it was first discovered by a French chemist Louis Camille Maillard who believed the Maillard reaction in foods can help cure diabetes. His assumption was wrong‚ however‚ the Maillard reaction is now known to give food flavor and make it look
