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.
Answer:
Yes, it does not have chemical properties.
Explanation:
Helium, as an inert element, cannot rearrange its electrons to form another chemical substances with another element, like a combustion or an acidification, even though it can form nuclear reactions, these are not considered chemical reactions, because it does not involve a rearrangement of the electrons but changes the nucleus of the element giving another elements.
Given:
P1 = 50 kPa
V1 = 5.0 L
P2 = 125 kPa
V2 = ?
Boyle's Law
P1V1 = P2V2
50 * 5 = 125 * V2
250 = 125 * V2
250 / 125 = V2
2 = V2
Answer is letter C. 2.0 L
