Pre-Lab Assignment: Empirical Gas Laws (Part 3) Name Section 1) In part 1, you will use a graduated cylinder that can hold up to 100-mL of a gas. Hydrogen gas will be generated by the reaction of magnesium in hydrochloric acid: Mg (5) - 2 HCl (aq) + MgCl2 (aq) + H (9) Assuming HCl is in excess does that put a constraint on the mass of magnesium that you will use in the experiment? Explain your answer without doing any calculations. b) Calculate the maximum amount of magnesium (grams) that you should use in your experiment, given that you will use a 100-ml graduated cylinder to collect the hydrogen gas. (Hint: Use the ideal gas law. What is the value of R? What are reasonable values for P and T?) c) Why should you wait a few minutes after the reaction to record the temperature of the gas
