Sectiоn 1: Fill in the blаnk (8 pts) Fill in the blаnk with the cоrrect аnswer. Accоrding to Arrhenius, a base produces [blank] when dissolved in water. An acid that contains two acidic protons is called [blank]. A [blank] solution has the maximum amount of solute dissolved, while an [blank] solution can still dissolve more solute. [blank] is the process of going from a more concentrated state to a less concentrated state. Molarity is defined as [blank] per [blank]. A [blank] acid completely dissociates in water. Section 2: True/False (5 pts) Answer true or false. If the answer is false, correct the statement. An Arrhenius acid produces OH- in water. % v/v is calculated by taking the mass of solute divided by the volume of solution. A solution is often opaque due to the larger solute particles. AgNO3 is soluble in water. Hexane (C6H14) will dissolve in water. Section 3: Multiple Choice (6 pts) Indicate the letter of the correct answer on your paper. Which of the following is a solution? milk salad dressing salt water Which of the following is an acid? NaCl HCl CCl4 What is the molarity of a solution made with 3.7g Ca(OH)2 in 834mL of solution? 4.4M 0.060M 0.068M Section 4: Short Answer (31 pts) Show all work. Be sure to clearly indicate your answer. A patient who weighs 180 lbs is to be given a medication, which should be administered at the dosage of 2 mL per kg of patient weight. How many L of the medication should be administered to the patient? Show ALL work, don't forget units and SF. (4 pts) 1 kg = 2.20 lbs A chemist starts with 50.0 mL of a 0.415 M NaCl solution. The chemist dilutes the solution to a new volume of 1.00 L. What is the new concentration of the solution? Show ALL work, don't forget units and SF. (2 pts) Consider the equation: Mg(s) + 2HCl(aq)
