The answer is Adsorbent

The adsorbent has a high affinity for solvent and the chemical components of the mixture.

Chromatography is a method of separation in which the mixture of substances is introduced into a mobile phase (solvent). The separation occurs as the solvent interacts with an adsorbent(stationary phase).

The extent of separation of the components of the mixture depends on the extent of interaction between the mobile and the stationary phase . This interaction also determines the retention factor (Rf) of the separation.

For a definition of chromatography, see

Answer:

Sulfur dioxide relased by the industry=

25%

Explanation:

The amount of sulfur dioxide relased by the industry can be calculated by looking at the values of the other; transport and electricity generation. Since electricity generated sulfur dioxide is 69% + 6% of transport that equals 75%. Pie diagrams always equal a total of 100%.

so simply you minus 75 from 100: 100-75=25%.
