Burning of sugar substance solubility in 100 ml water density (g/ml) melting point (°c) sugar 200 g 1.2 185 oxygen 0.9 mg -218.4 product 1 0.16 mg -56 product 2 0.17 g 1.0 0 from the data table, describe how you know a chemical reaction took place between sugar and oxygen. a) the solubility decreased. b) the density was not available on one of the reactants. c) because sugar will dissolve in water and change the solubility. d) the chemical and physical properties of the products do not match the properties of the reactants.
