Sectiоn 1: Fill in the blаnk (11 pts) Fill in the blаnk with the cоrrect аnswer. The prоducts of a neutralization reaction are always [blank] and a [blank]. Pressure and temperature are [blank] related. The term used to describe a solution where the solvent is water is [blank]. The molar mass of chlorine gas is [blank]. The [blank] are left out of the net ionic equation. Charles’ Law compares [blank] and [blank]. [blank] ‘s number is equal to 6.022 x 1023. To convert between substances in stoichiometry, you need the [blank]. In a chemical equation, reactants are always written on the [blank] of the reaction arrow. Section 2: True/False (4 pts) Answer true or false. If the answer is false, correct the statement. You can use molar volume of a gas under any conditions. PbSO4 is a soluble compound. In a limiting reactant problem, you only need to do one stoichiometric calculation (flow chart). Coefficients do not need to be integers (whole numbers). Section 3: Multiple Choice (8 pts) Indicate the letter of the correct answer on your paper. Which of the following is not a unit of pressure? Pa mL Hg atm Which gas law is not a two-condition (before and after) law? Ideal Gay-Lussac’s Combined How many CH4 molecules are in 14.8 g of CH4? 5.56 x 1023 CH4 molecules 6.85 x 1023 CH4 molecules 6.53 x 1023 CH4 molecules Which statement is TRUE about kinetic molecular theory? A single particle does not move in a straight line. The attractive forces between particles are very weak. The average kinetic energy of a particle is not proportional to the temperature. Section 4: Short Answer (27 pts) Show all work. Be sure to clearly indicate your answer. Balance the following reactions. (6 pts, 2 pts each) SnO2 + H2
