Butane gas, C4H10, is combusted to produce carbon dioxide and water vapour. If 0.75 mol of butane are reacted, how many moles of carbon dioxide are produced?
A gases in a hair spray can are at a temperature of 27°C and a pressure of 30 mmHg. If the gases in the can reach a pressure of 90mmHg, the can will explode. To what temperature must the gases be raised in order for the can to explode? Assume constant volume
How many moles of watr
gas?
are needed to produce 5.00 x1022 molecules of hydrogen
Liquid octane (CH3 (CH2)6 CH3) reacts with gaseous oxygen gas (02) to produce gaseous carbon dioxide (CO,) and gaseous water (H, O). What is the
theoretical yield of water formed from the reaction of 42.3 g of octane and 136. g of oxygen gas?

A glass in a fixed container is at a pressure of 4 atm and a temperature of 27 0C. What will be the pressure if it is heated to a temperature of 177 0 C?
40 cm 3 of an ideal gas at a temperature of 27 0 C is heated to 227 0 C in a freely expandable vessel. Determine the new volume of the gas.
A gas at a temperature of 127 0C is heated in a freely expandable container until its volume doubles. What is the new temperature of the gas?
A bubble rises from the bottom of a lake 30m deep and is four times its original volume just before breaking the surface. If the temperature is constant and the pressure at the bottom of the lake is p, what is the pressure at the water surface?
A bicycle pump of volume 72 cm3 is filled with air at a pressure of 0.1 MPa. The volume is reduced to 30 cm3. No air leaks from the pump and the temperature stays constant. Calculate the pressure of the compressed air.
