Help for an Aussie chemistry student!!

Post by cbaske02 »

2 questions:
Q1 Aluminium reacts with hydrochloric acid according to the equation
2Al+6H=2Al3+ +3H2. What volume of 0.471M HCl solution is required to react with aluminium to produce 32.2 L dry H2 gas at 295.15K and 103kPa?
I just dont get it...
and Q2 If an inflated balloon has a volume of 1.510 L at sea level where the temp is 298.15K and the preasure is 1.200atm. The balloon rises at a height of 4.16km where the temp is 242.15 and the preasure is 0.250atm. What is the final volume of the balloon?
Please help me!! :?
