How does chromatography separate substances

Chromatography is really a method for isolating out a blend of synthetics, which are in gas or fluid shape, by giving them a chance to crawl gradually past another substance, which is regularly a fluid or strong.  

Explanation:

Chromatography can be utilized to isolate blends of hued mixes. Blends that are reasonable for division by chromatography incorporate inks, colors and shading operators in nourishment. Basic chromatography is completed on paper. ... Diverse parts of the blend will move at various rates.There are four primary sorts of chromatography. These are Liquid Chromatography, Gas Chromatography, Thin-Layer Chromatography and Paper Chromatography. Fluid Chromatography is utilized on the planet to test water tests to search for contamination in lakes and waterways.

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
