CBE BIOL 1010 Module 3 2023/2024 updated to pass

CBE BIOL 1010 Module 3Matter - correct answer Any substance that occupies space and has mass Element - correct answer Unique forms of matter with specific chemical and physical properties that cannot break down into smaller substances by ordinary chemical reactions Atom - correct answer The smallest unit of matter that retains all of the element's chemical properties. Atomic Number - correct answer The number of protons in the nucleus of an atom Atomic Mass - correct answer The mass of an atom; approximately equal to the number of protons plus the number of neutrons Isotope - correct answer Different forms of an element that have the same number of protons but a different number of neutrons Electron Shell - correct answer A way of visualizing the electrons of an atom; may be thought of as an orbit around the atomic nucleus Compound - correct answer a chemical substance consisting of two or more different chemically bonded elements Ion - correct answer An atom or molecule that has a non-zero net electrical charge. May be positively or negatively charged Ionic Bond - correct answer A bond between ions (charged atoms or molecules) with opposite charges Covalent Bond - correct answer A chemical bond that involves the sharing of electrons between atoms Polar Covalent - correct answer A chemical bond that involves unequal sharing of electrons between atoms Hydrogen Bond - correct answer A weak bond between slightly positively charged hydrogen atoms and slightly negatively charged atoms in other molecules Van der Waals interaction - correct answer A very weak interaction between molecules due to temporary charges attracting atoms that are very close together Specific Heat Capacity - correct answer the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius Heat of Vaporization - correct answer the amount of energy required to change one gram of a liquid substance to a gas Solvent - correct answer a substance that dissolves a solute (a chemically distinct liquid, solid or gas), resulting in a solution Solute - correct answer The minor component in a solution, dissolved in the solvent. Solution - correct answer A homogeneous mixture composed of two or more substances Dissociation - correct answer A process in which molecules (or compounds) split into smaller particles such as atoms or ions, usually in a reversible manner. Cohesion - correct answer The action or property of like molecules sticking together, being mutually attractive Adhesion - correct answer the tendency of dissimilar particles or surfaces to cling to one another Surface Tension - correct answer Tension at the surface of a body of liquid that prevents the molecules from separating; created by the attractive cohesive forces between the liquid's molecules
