This leads to an answer of SO2. 38. C The total molar mass of this compound is 100. The nonmetals, one hydrogen atom, one carbon atom, and three oxygen atoms have a total mass of 61. Therefore, the nonmetals make up 61% of the total mass. 39. A Boiling and freezing point are affected most by a solution that contains the greatest number of particles. 6 molal. This is greater than any of the other choices. 40. E Dry ice (solid carbon dioxide), iodine crystals, and naphthalene (mothballs) all sublime and change from solid to gas phase without any apparent liquid phase.
115. T, T, CE Lithium is a metal and will lose electrons, undergoing the process of oxidation. Any substance that has been oxidized can be considered to be a reducing agent. 26. 5 gives us two moles of NaCl. 500 L (M = moles/liters) which gives a concentration of four molar. Using the equation M1V1=M2V2, if the volume of the solution is doubled the concentration of the solution will be halved. This gives a ﬁnal answer of 2 M NaCl(aq). 27. B In this molecule there is one triple bond. The ﬁrst bond of the triple bond is a sigma bond, the other two bonds of the triple bond are called pi bonds.
Which one of the following demonstrates a decrease in entropy? (A) Dissolving a solid into solution (B) An expanding universe (C) Burning a log in a ﬁreplace (D) Raking up leaves into a trash bag (E) Spilling a glass of water 42. Which of the following substances is/are liquid(s) at room temperature? I. Hg II. Br2 III. Si (A) I only (B) II only (C) I and II only (D) II and III only (E) I, II, and III 37. A compound’s composition by mass is 50% S and 50% O. What is the empirical formula of this compound?
