Suppose 30 ml of oxygen and 75 ml of hydrogen are mixed and ignified. What volume of gas remained unreacted and what gas will it be?

1. Give reasons for the following: when '30 ml' of ethanol and '30 ml' of water are mixed, the volume of resulting 'solution. is more than '60 ml'. Ans: In ethanol and water, the molecules are by. drogen bonded. When these are mixed 't 0' form a solution, each liquid tends to break the hydrogen bonds of the other liquid. The attractive forces decrease. The total volume of the solution becomes more than '60 m'

If volume containing gas' is compressed to half, moles of gas remained in the vessel will be:

10 ml of a gaseous hydrocarbon were mixed with 100 ml of oxygen and exploded in a eudiometre tube. The volume of residual gases was 95 ml of which 20 ml was absorbed by caustic soda and the remainder by pyragallol. The molecular formula of the hydrocarbon is

What is the volume of ideal gas at absolute zero of temperature?

What relation do you arrive at between pressure and volume of the gas?
