The answer is "chemical weathering." Lichen is fungi that can grow on rocks and lichen produces chemicals which breaks down the rock which contributes to weathering. Weathering is the breaking down of rocks naturally which can take thousands of years to happen.

Hope this helps.

Answer:

Biphenyl

Explanation:

The reaction of bromo benzene with magnesium-ether solution yields a Grignard reagent.

The byproduct of this reaction is biphenyl. It is formed when two unreacted bromobenzene molecules are coupled together.

Hence, It is advised that the bromobenzene solution be added slowly to the magnesium-ether solution so that it isn't present in a high concentration, thus reducing the amount of biphenyl by-product formed.
