When aluminum reacts ith hydrochloric acid, hydrogen gas and aluminum ions are formed. A 0.0234 gram sample of aluminum is added to 10 ml of .432 M HCl solution The gas collected over water.
a)Write a balance net ionic equation for the reaction that takes place (Balance the charges)
b)How many moles of H are added?
c) What is the volume of hydrogen gas obtained if the temperature. is 28 Celsius and the total pressure is 742 mm hg? (Vapor presure of water at 28c=28.35 mm hg)
Answers:
1.2Al (s) + 6H+ (aq) -> 2Al3+ (aq) + 3H2 (g)
2. 4.32 x 10-3 mol H+
3. 8.67 x 10-4 mol Al
4. 34. 2 mL
