1. In a neutralization reaction, the number of moles of hydrogen ions (H+) equals the number of moles of hydroxide ions (OH-). A) True B) False (Correct answer: A. True. The reaction is typically written as H+ + OH- → H2O) 2. Which of the following is not a required step in balancing redox reactions? A) Assigning oxidation numbers B) Identifying the reducing and oxidizing agents C) Balancing the atoms other than hydrogen and oxygen D) Balancing the electrons transferred (Correct answer: C. Balancing the atoms other than hydrogen and oxygen) 3. The molarity of a solution is calculated by dividing the moles of solute by the volume of solvent in liters. A) True B) False (Correct answer: A. True. Molarity (M) = moles of solute / liters of solvent) 4. What is the molarity of a solution containing 0.5 moles of solute in 1 liter of solvent? A) 0.5 M B) 1 M C) 0.25 M D) 2 M (Correct answer: B. 1 M. Molarity = 0.5 moles / 1 liter) 5. The percent composition of a compound can be calculated by dividing the mass of each element in the compound by the total
