What is a solution? - correct answer A homogeneous mixture made up of two or more substances that do not chemically combine; instead, the substances mix uniformly in the solution. What is a solvent? - correct answer The substance present in the largest quantity by volume, usually water. What is a solute? - correct answer The substance that is dissolved in the solvent. How do you find the empirical formula of a compound? - correct answer First, determine mol by dividing the percent comp or mass of elements by their molar mass, then divide the mol values by the smallest mol value. How do you find the molecular formula of a compound? - correct answer First, determine the mass of the empirical formula, then divide the mass of the molecular formula by the mass of the empirical and finally multiply the empirical formula by the ratio obtained between the masses. What is the equation to find percent yield? - correct answer (laboratory yield/theoretical yield) * 100 = percent yield What is the equation to find percent error? - correct answer (|lab value-accepted value|/accepted value) * 100 = percent error What is the full electron configuration of Sulfur (S)? - correct answer 1s²2s²2p⁶3s²3p⁴ What is the compound name for iron (III) hydride? - correct answer FeH₃ What does NH₄OH dissociate into? - correct answer NH₄⁺ and OH⁻ List the seven strong acids. - correct answer Hydrochloric acid (HCl), Hydrobromic acid (HBr), Hydroiodic acid (HI), Nitric acid (HNO₃), perchloric acid (HClO₄), chloric acid (HClO₃), sulfuric acid (H₂SO₄) List the six strong bases. - correct answer Sodium hydroxide (NaOH), Lithium hydroxide (LiOH), Potassium hydroxide (KOH), Calcium hydroxide (Ca(OH)₂), Strontium hydroxide (Sr(OH)₂), Barium hydroxide (Ba(OH)₂) Are compounds of Group 1 metals soluble or insoluble? - correct answer Soluble Are common ammonium ions soluble or insoluble? - correct answer Soluble Are common nitrates soluble or insoluble? - correct answer Soluble Are common acetates soluble or insoluble? - correct answer Soluble Are common chlorates soluble or insoluble? - correct answer Soluble Are common perchlorates soluble or insoluble? - correct answer Soluble List the insoluble fluoride compounds. - correct answer MgF₂, CaF₂, SrF₂, BaF₂, PbF₂ List the insoluble halide compounds. - correct answer AgX, Hg₂X, PbX₂
