Question 1 1. Which of the following can impact the reaction rate?

Question 2 2. A Magnesium atom is most likely to have what charge as an ion?

Question 3 3. Determine the actual yield if the theoretical yield is 12 g and the percentage yield is 90%.

Question 4 4. What is titration?

Question 5 5. Which of these elements has the smallest atomic radius?

Question 6 6. According to Bronsted-Lowry, a conjugate base is:

Question 7 7. What is the correct formula for determining the voltage of an electrochemical cell?

Question 8 8. What is the function of an electrochemical cell?

Question 9 9. What is corrosion?

Question 10 10. A lab technician dissolved 2 mol of X in 1 liter of water in order to make a 2 M solution. What did they do wrong?

Question 11 11. Suppose you were teaching a science class to middle school students. Because you want to show them an impressive chemical reaction, you decide to dissolve zinc in hydrochloric acid. You add more acid than usual and throw in pieces of zinc. What factor is not going to impact the reaction rate?

Question 12 12. You conduct an experiment that requires the creation of an ammonia solution. You do this by reacting 50.0 L of nitrogen gas with excess hydrogen gas at STP to create ammonia gas using the Haber process given by the following reaction: N2 (g) + 3H2 (g) → 2NH3 (g). Assuming the reaction had 100% yield, you then bubble the ammonia into 5.0 L of water. What is the molarity of the resulting ammonia solution?

Question 13 13. If 1.605 kg of mercury are used in the reaction 2Hg + O2 --> 2HgO, what is the mass of HgO, in kilograms, that are produced?

Question 14 14. What is the shape of a Boron Trifluoride molecule, BF3?

Question 15 15. Alcohol and water are best separated from one another by:
