In two vessels of 1 litre each at athe same temperature 1g of `H_(2)` and 1g of `CH_(4)` are taken. For these gases:

In two vessels of 1 litre each at the same temperature lg of H_(2) and 1 g of CH_(4) are taken, for these :

Two vessels of the same size are at the same temperature. One of them contains 1 g to H_2 gas, and the other contains 1 g to N_2 gas. Which of the vessels is under greater pressure or and why ?

The ratio of kinetic energy of 2g of H_(2) and 4g of CH_(4) at the given temperature is "

When two gases having volumes 1 litres and 2 liters are at the same temperature, then the ratio of the average kinetic energy of the molecules in the two gases

One litre of O_(2) and one litre of h_(2) are taken in a vessel of 2 litre capacity at NTP The gases are made to combine to form water . The amount of gas left in vessel is .

One litre of O_(2) and one litre of h_(2) are taken in a vessel of 2 litre capacity at NTP The gases are made to combine to form water . If the vessel is heated to 100^(@)C the total pressure is .

A and B are two identical vessels. A contains 15 g of ethene at 298 K and 1 atm. The vessel B contains 75 g gas X_2 at the same temperature and pressure. The vapour density of X_2 is :

The total number of electrons in 1.6 g of CH_(4) to that in 1.8 g of H_(2)O
