Processes used in separation of a substance into its components and the removal of impurities.

Methods of separation include:

1. Paper chromatography - used in food industry to identify chemicals namely food coloring agents or inks.

2. Filtration - commonly used to separate an insoluble solid from a liquid e.g. sand from water.

3. Evaporation -   used in separating a mixture of a soluble solid and a solvent through heating until the solvent evaporates leaving behind the solid residue.

5. Magnetism - used to separate a mixture of two solids with one of them having magnetic properties. Gold can be separated from iron using this method.

bazaltina [42]

Answer:

Impurities will be trapped in the crystals of the benzoic acid crystallized in this manner.

Explanation:

After benzoic acid is dissolved in hot water, it should have been allowed to cool gradually before it is transferred into an ice bath.

This gradual cooling will aid the separation of impurities so that when the vessel is now submerged in an ice bath, only pure benzoic acid is recrystalized.

If the vessel is immediately submerged into an ice bath, impurities will be trapped in the crystals of the benzoic acid.

lutik1710 [3]

Answer:

The release of methane from thawed permafrost.

Explanation:

The complete question is

A group of scientists in Alaska notices that not only have atmospheric CO2 levels increased at their sampling site but so too have methane levels. What could account for this increase in methane levels?

- None of the answer options is correct.

- The release of methane from thawed permafrost.

-A decrease in beef production near the researchers' sampling area.

-The melting of permafrost accompanied by the thawing of methane-producing bacteria.

-The failure of rice paddies to be established in Alaska, given its climate.

Permafrost regions like the arctic circle hold a large supply supply of methane in their soils and their seas. Ordinarily, this methane should be gradually released naturally over a long period of time, but the effects of global warming is making these permafrost to thaw at a much faster rate, accelerating the release of methane into the atmosphere. The dark side is that methane is about 80 times more deadly when compared to CO2 in its contribution to the green house effect on earth.
