Answer:
chromatography
Explanation:
Chromatography is one of the powerful technique that is used to separate the mixed components of liquid or the gas mixtures.
In this technique the separation of the mixture by passing the mixture in some solution or some suspension through the medium where the components are made to move at some different rates.
The basic idea in this experiment is that the mixture sample is in mobile phase and it is forced either by pumping or by gravity or by capillary action through the stationary phase to separate the mixture.
Answer:
True.
Explanation:
Newton's First Law of Motion states that every object continues in it's state of rest or of uniform motion in a straight line unless acted upon by an external force.
Density of cylinder is 4.82 g/cm³.
<h3>What is density of a substance?</h3>
Density is the ratio of the mass and the volume of a substance
The density of the cylinder is:
mass of cylinder = 50.12 g
volume of cylinder = πr²h
r = 1.62/2 = 0.81 cm
h = 5.04 cm
volume of cylinder = 22/7 * 0.81² * 5.04
volume of cylinder = 10.39 cm³
Density of cylinder = 50.12 g/10.39 mL
Density of cylinder = 4.82 g/cm³
In conclusion, density of a substance is the ratio of mass and volume of the substance.

The thickness of the ozone layer (for earth) and the atmosphere.
Mercury is the closest planet to the sun but it isn’t the hottest because it has no atmosphere. Although Venus is the second planet from the sun, it is the hottest because of it’s thick atmosphere and the clouds that trap heat in.
