3. Hydrochloric acid reacts with aluminum metal to produce hydrogen gas. 2AI (s) + 6HCI (aq) → 2AICI3 (aq) + 3H2 (g) a) How many moles of H2 gas are produced by the reaction of 12.8 g Al metal with excess HCI? Show your work including all unit conversions. Hint: you are going to need the molar mass of Al from periodic table because you have to calculate moles gf Al from grams of Al. Recall mol-to-mol ratio from Unit 2.3 b) How many liters of H2 gas can be collected if the reaction occurs under STP conditions? Show your work. (Recall that STP is 'standard temperature pressure conditions'. Under these conditions, 1 mole of any gas has a volume of 22.4 L)
