I think mm is not a unit of pressure
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.
In order the words are:
living, nonliving, biotic, plants, animals, abiotic, moisture, temperature, producers, nonliving, autotrophs, consumers, eating, and heterotrophs.
Outer electrons because they revolve around the nucleus and can be multiple more than one
