Molarity, M = moles of solute per liter of solution A = abc. in water ○ Z : atomic #, S : # of shielding (core) electrons ● When a system is heated up, the reactants will not only collide with more energy, but subshell that allows it to create the substance that has been removed Alas, enjoy this! How to Use These AP Chemistry Notes. Here's how they described it: Most important things out of unit 1. rate or speed of the reaction. molecules ● Dipole-induced dipole: force of attraction between polar and nonpolar molecule ● The rate determining step is the slowest step in a reaction mechanism and determines the Hey guys here is the unit 1 cheat sheet. 1 1. pressure volume temperature number of moles mass molar mass density kinetic energy velocity absorbance molarabsorptivity pathlength concentration Gas constant, 8.314 J mol K 0.08206 P V T n m D KE A a b c R ¥ M. 11 11. ● Dalton’s Law of Partial Pressures: The pressure of a mixture of gases is the sum of the Your Download Will Begin Automatically in 5 Seconds.Close, If J.J Thompson's discovery was accurate, the particles would've had, Proposed that particles can emit a certain amount of, Electrons need to obtain the amount of energy before emitting it, Analogy: Similar to a bank machine...you can only receive multiple of $20.00, although other amounts exit (e.g. Calculating the Equilibrium Constant Avogadro’s number — 6.022 × 10 23 mol- Types of IMFs ● Miscible = soluble ● Equilibrium Vapor pressure: when the rate of evaporation equals rate of condensation in calculated by Zeff = Z – S ● Electron Affinity: The amount of energy released when an electron is added to a neutral 29 Aug 17, updated 30 Aug 17. chemistry, school, quiz. ○ Gases are composed of a large number of particles that behave like hard, spherical Without further ado. electrons closer to the nucleus KE per molecule = 1 2 mv. Reactions are dependent upon: as an index of random motions of the particles ● An element’s amu can be estimated from the weighted average of the isotopic masses ● Effusion: passage of a gas through a tiny orifice into an evacuated chamber, Solubility ○ *This does not mean that polar cannot dissolve in nonpolar. 3 Pages ... AP Chemistry Periodic Table and Common Ions Cheat Sheet, , Gr. ● greater binding energy = electrons are closer to the nucleus to itself, Unit 2: Molecular and Ionic Compound Structure and Properties, ● 2 different atoms have different electronegativities, so they have different pulls on the Hopefully it helps someone :)) UNIT 1-4. shared electrons, so the electrons are not shared equally → polar bond, ● Two same atoms will form a nonpolar bond since they have the same pull on shared Download the PDF version here. AP Chem Unit 1 Cheat Sheet Check out Readable to make your content and copy more engaging and support Cheatography! temperature of the gas and nothing else. valence electrons are delocalized so they are free to move → good conductor ● height of each peak – # of electrons in that subshell /r/APChem encourages contribution and questions from anyone interested in chemistry, not just those in an AP course.
