monomers join together to form polymers Answer Polymerization 6 What are the four main types of organic macromolecules Answer Carbohydrates lipids proteins and nucleic acids 7 What is the primary function of carbohydrates Answer Carbohydrates are the primary source of energy for living organisms 8 What is the primary function of lipids 3 Answer Lipids provide energy storage insulation and protection for cells 9 What is the primary function of proteins Answer Proteins have a wide range of functions including structural support enzymatic catalysis and transport 10 What is the primary function of nucleic acids Answer Nucleic acids store and transmit genetic information Inorganic Chemistry 1 What are the four main types of inorganic compounds Answer Acids bases salts and oxides 2 What is the difference between a strong acid and a weak acid Answer A strong acid completely ionizes in solution while a weak acid only partially ionizes 3 What is the difference between a strong base and a weak base Answer A strong base completely dissociates in solution while a weak base only partially dissociates 4 What is the process of dissolving a substance in water called Answer Hydration 5

name of the chemical reaction that involves the transfer of electrons Answer Redox reaction 7 What is the difference between an oxidation reaction and a reduction reaction Answer Oxidation is the loss of electrons while reduction is the gain of electrons 8 What is the law of multiple proportions Answer The law of multiple proportions states that when two elements form more than one compound the masses of one element that combine with a fixed mass of the other element are in the ratio of small whole numbers 4 9 What is the name of the process by which a substance changes from a liquid to a gas Answer Vaporization 10 What is the name of the process by which a substance changes from a gas to a liquid Answer Condensation Analytical Chemistry 1 What is the difference between qualitative analysis and quantitative analysis Answer Qualitative analysis identifies the components of a sample while quantitative analysis determines the amount of each component 2 What is the name of the
