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

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
