In water, carbonate will undergo the following reaction:CO32-(aq) + H2O(l) → HCO3-(aq) + OH-(aq). Red litmus paper will turn blue in a base.HCl reacts with CO32- to form...CO2(g)higher Rf value meansLESS polar: move farther up the plateLower Rf value meansMORE polarThe number of neutrons can be found by...mass # - atomic #In a neutral atom, the number of electrons equals the number of what other part?protonsUnder acidic conditions, the hydroxyl group is protonated such that the leaving group is nowwater- a better LG than hydroxide ionbinary ionic compounds are made up ofa metal + nonmetalvast majority of covalent compounds are comprised exclusively ofnon-metallic elementsaqueous solutions of ionic compounds conduct electricityempirical formula showslowest whole number ratio of moles of each element in a mole of the compound, or the corresponding number of atoms per molecule.Ionization Potential (IP)energy to remove an electron from an atomA sparingly soluble metal hydroxide, M(OH)2 has a molar solubility of S mol/L at 25°C. Its Ksp value is:The Ksp for a substance, AaBb, equals [A]a[B]b. The Ksp for M(OH)2 = [M][OH-]2. If the solubility of M(OH)2 is S mol/L, then [M] = S mol/L and [OH-] = 2S mol/L. The Ksp = S(2S)2 = S(4S2) = 4S3. Thus, D is the best answer.Because heat is liberated, the dissolution of solid NaOH is an exothermic process for which the enthalpy change is...ΔH < 0As NaOH dissolves, the system becomes more random (disordered), which corresponds to a positive entropy change, and ...ΔS > 0free energy change is given byΔG = ΔH - TΔS ΔG < 0 when the value of ΔH is (-) and that of ΔS is (+), because the absolute temperature T is always (+).Molarity equationM = moles of solute/liters of solutionWhat is the geometry of the hexafluoroaluminate ion (AlF6^3-)?Arrhenius acidProduces H+ ions when dissolved in waterArrhenius baseProduces OH- ions when dissolved in waterBronsted-Lowry acidProton donor (H+ donor)Bronsted-Lowry baseproton acceptor (H+ acceptor)Lewis acidelectron pair acceptorLewis baseelectron pair donorThe abbreviation ppm stands forparts per millionIt is assumed that the molecules in an ideal gas have no _______ and that there are no interactions between __________volume; molecules
