  • Chemical Formula Lab Report

    The purpose of this lab is to calculate the chemical formula of a hydrate compound made up of copper, chlorine, and water molecules by using the law of definite proportions. The water of hydration of the copper chloride hydrate sample will be determined as well as the mass of copper and chlorine through a chemical reaction. The results will be used to calculate the moles of copper and chlorine and then the empirical formula of the compound. Techniques used: In this experiment, different…

  • Ammonium Perchlorate Lab Report

    Figure 3. Possible reaction mechanism for the decomposition of ammonium perchlorate. Based on the findings from all of the used techniques, the species formed in the beginning are ammonium ion, oxygen and chlorine species. The decomposition products of ammonium ion were hydroxylamine, ammonia and nitrogen dioxide. The perchlorate ion loses one of the oxygen atoms and forms chlorate ion. The ammonia is lost in reaction through formation of hydroxylamine, which is formed in reaction between…
