Question

A.) Iron reacts with hydrochloric acid to produce Iron (II) chloride and hydrogen gas. If 2.2 grams of iron react with excess hydrochloric acid in a 10.0 L flask at 25 degrees Celsius, what is the pressure of the hydrogen gas in this flask in mm Hg?

Fe (s) + hydrochloric acid (aq) ------> iron (II) chloride (aq) + hydrogen gas

B.) Calculate the volume in mL of 6.5 M hydrochloric acid required to react with 2.2 grams iron in the above reaction.
