Chemical Reactions Formal Lab Report By Mason Ely Background We did this lab on Chemical Reactions and to study and learn about the law of conservation of mass. Lab stations tested each method, synthesis, double displacement, decomposition, and single displacement, to study the law of conservation of mass. The law of conservation of mass is the law that states that matter cannot be created nor destroyed without human mistake in a chemical reaction. In station A we tested the chemical reaction of synthesis; synthesis is the chemical reaction where two or more elements or compounds form one compound product. In station B we tested the chemical reaction of decomposition; decomposition is the chemical reaction where the chemical compound is separated into elements or simpler compounds. In station C we tested the chemical reaction of double displacement; double displacement is the reaction where two compounds are replaced by two other compounds. In station D we tested the chemical reaction of single displacement; single displacement is when one compound is replaced by another compound. Each station is testing the law of conservation of mass by using each method in the lab. Purpose The purpose for this lab is to study the law of conservation of mass by using synthesis, decomposition, single replacement, and double replacement. Hypothesis Station A: If we see the magnesium ribbon create a bright white flame, then we know that a reaction has occurred. Station B: if the wood splint is extinguished, then we know that carbon dioxide gas is present. Station C: if we hear a pop when we put the wood splint around the mouth of the tube, then we know that hydrogen gas is present. Station D: if we see that some sort of shape is made, then we know that a chemical reaction has occurred. Materials Station A: Bunsen burner, Matches,
