The drain cleaner, Drainex contains small bits of aluminum which react with caustic soda to produce dihydrogen. What volume of dihydrogen at 20∘C and one bar will be released when 0.15 g of aluminum reacts?
An LPG cylinder weighs 14.8kg when empty. When full it weighs 29.0kg and the weight of the full cylinder reduces to 23.2kg. Find out the volume of the gas in cubic metres used up at the normal usage conditions and the final pressure inside the cylinder. Assume LPG to be n-butane with normal boiling point of 0∘C.
A gas in a closed container will exert much higher pressure due to gravity at the bottom than at the top.

For gaseous reactions, the rate is expressed in terms of dP/dt instead of dc/dt or dn/dt (where c is the concentration and n the number of mol). What is the relation among these expresisons ?
Which one of the following V,T plot respresents the behavlour of one mole an ideal gas at one atap ?
