Stociometry practice problem HELP
« on: October 07, 2011, 04:12:55 PM »
The reaction of solid aluminum with hydrochloric acid produces Hydrogen gas and aqueous aluminum chloride. Write a balanced reaction.

A. If a 2.15 g sample of Aluminum is dissolved in 250 ml of 0.0150 M HCL , how many grams of Hydrogen gas can be produced?

B. What is the limiting reactant?


C. How many grams of ALCL3 can be produced from the same reactants? And how could it be recovered?

Can you show me the steps on how to do to do these? I really need to know how to do this. THANK YOU!

Well, you need to show your attempts in order to receive any help. Hmm... So, do you know the chemical formulae of the compunds (Aluminium, Hydrochloric acid and Aluminium Chloride)?

Write down the equation once you know the chemical formulae and balance it.
