An evacuated cylinder has a volume of 50 liters. if 20 liters of nitrogen gas and 20 liters of oxygen gas are pumped into this evacuated cylinder, how much of the cylinder is filled with the two gases?

The cylinder will be 40 liters filled with the two gases.

Explanation: We are given an evacuated cylinder which can hold upto 50 liters and we are putting 20 liters of oxygen and 20 liters of nitrogen gas into it.

Assuming that the gases are behaving ideally, so according to the Raoult's Law there will be no change in the volume if the mixing of gases takes place.

So, the total volume occupied by the gases in the evacuated cylinder will be = (20 + 20) liters = 40 liters.

Hence, the cylinder will be 40 liters filled with the two gases.

all of the cylinder because gases expand to fill the container

-be a crystalline solid

- be soluble in water

-conduct electricity

hope this : )

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
