1. I ate/drank milk. The macromolecular level of milk is carbohydrate‚ fat‚ and protein. Protein is called a casein which is di –is the lactose‚ Carbohydrate is Mono- is the glucose (simple sugar)‚ Fat is a straight chain fatty acids that are saturated and is poly – I think. 2. The monomer for the protein is amino acid – milk has all 9-essential amino acids. The monomer for the carbohydrate is monosaccharide‚ which is a simple sugar. The monomer for the lipid is fatty acid in milk its triglyceride

g. methane‚ ethane and propane) have only single bonds‚ and are said to be saturated; alkenes (e.g. ethene and propene) and alkynes (e.g. ethyne) have carbon-carbon double or triple bonds‚ and are said to be unsaturated. Aromatic hydrocarbons are cyclic compounds whose structure is related to that of benzene‚ with six-electrons in a six-membered ring. For this experiment‚ hexane will be used as an example of saturated hydrocarbons (alkanes)‚ cyclohexene will be used as an unsaturated hydrocarbon

will be organic solvent that is insoluble in water.The organic solvent used have to be volatile because it can be easily removed by evaporation when forming crystals. Phenolic compounds will undergo salt formation with sodium hydroxide solution‚ NaOH.Therefore‚sodium hydroxide solution is allow to use to extract a carboxylic acid or phenolic compound from its solution in an organic solvent.An organic solvent can be used to remove organic impurities from a carboxylic acid or phenol dissolved in aqueous

hypothesis for reaction 3 is that the moistened litmus paper changes color. The odor will be a chemical odor that smells bad. The burning splint will be extinguished. Reaction 4- My hypothesis for reaction 4 is that adding hydrochloric acid to solid calcium carbonate produces bubbles maybe. When burning the splint is placed on the test tube‚ the flame is extinguished. Reaction 5- My hypothesis for reaction 5 is that mozzy zinc in the test tube will make smoke come out of the tube Reaction 6 - My hypothesis
