LAB REPORT Introduction: In a chemical change‚ the identities of substances change and new substances form. In an equation the substances on the left are the reactants. The substances on the right are the products. In this experiment the objectives are to observe evidence that a chemical change has taken place. Infer from observations that a new substance has been formed. Identify and record observations that show energy is involved in chemical change observe the color‚ solubility of some substances

MACROMOLECULS LAB: What are the mystery powders? Period: 4 Asia Enoch Introduction: A carbohydrate is an immediate form of energy in your body. Monomers is smaller than a polymer. For carbohydrate the monomer is sugar and the polymer is a polysaccharides. Carbohydrates are important to our body because we need to use energy. The purpose of this lab is to figure which one is the monomer and which one is the polymer. Hypothesis: If I place two drops of iodine into the mystery powder‚ it
