Question

Why are different materials separated by chromatography? Each material is a different compound in the mixture Each material has a slightly different color than the others in the mixture Each material moves at a slightly different speed from others in the mixture Each material moves at a similar speed to others in the mixture An atom that has gone from an oxidation state of -2 to -1 in a reaction has undergone what process? It has reduced. It has oxidized. It has become more acidic. It has become more basic. What is Avogadro's Law? Equal temperatures of gases at the same pressure contain the same number of gas particles. Equal pressures of gases at the same temperature contain the same number of gas particles. Equal volumes of gases at the same temperature and pressure contain the same volume of gas particles. Equal volumes of gases at the same temperature and pressure contain the same number of gas particles.

Explanation / Answer

38.

option C is the correct answer

Chromatography will work based on the absorption

if both compounds are having the different polarities they will move differently in column

based on this movement only we can separate the compounds

39.

option B is correct

oxidation number changed from -2 to -1 means oxidation state increased

which means oxidation takes place

means it has oxidized.

option D is correct answer
