CHEM LAB 116 Final Review Molarity – the number of moles per liter of solution Molality – the number of moles per kilogram of solvent Density = m/v The number of protons distinguishes one element from another element. Electrons are responsible for most of the size of an atom. A nuclear reactor is very much like a steam engine. An atom is 1x10^-10m, or 1 angstrom, 0.1 nanometers A proton/neutron/nucleus is 1x10^-15m, much less than 0.1 nanometers A micrometer is 1x10^-6m A nanometer is 1x10^-9m Mass defect is the difference between the calculated and experimental mass of a nucleus. An element is the simplest form on matter. Parts of a nuclear reactor: Core (reactor tank) – contains the uranium fuel (in tons) Moderator (control rods) – controls rate of reaction by slowing down neutrons Control Rods (also moderator) – absorbs almost all neutrons when engaged Coolant (pipes) – carries away heat to a boiler where steam is made Shielding (whole containment structure) – steel and concrete to prevent radiation from escaping Bioavailable is a term used to describe when a substance is in a form that can cause a biological effect Copper Cycle: (1) Cu + HNO3 Cu(NO3)2 + NO2 + H2O Copper dissolved, bright blue solution, yellow smoke Redox Reaction (2) Cu(NO3)2 + NaOH Cu(OH)2 + NaNO3 Blue slush precipitate (3) Cu(OH)2 CuO + H2O Muddy black substance (4) CuO + H2SO4 CuSO4 + H2O Light blue-turquoise liquid (5) CuSO4 + Zn Cu + ZnSO4 Zinc turned copper-colored
