Answer:
Mixture
Explanation:
When a prospector scoops up part of the stream bed, the pan contains stream sediments.
In, 1937 Lawrence, in operating his cyclotron, bombarded a molybdenum-96 foil with deuterium ions (2h), producing for the first time an element not found in nature. He was initially unaware that the radioactivity produced by the "bombarded foil" was not from molybdenum but from a new, artificial element. It was his cooperation with Italian-American physicist <span>Emilio Segrè </span>that allowed the new element to be discovered. The answer is Technetium: Tc
Answer:
2-Methyl-5-nitrothiophene
Explanation:
The 2- and 5-positions of thiophene are the most susceptible to electrophilic aromatic substitution.
Thus, the major product from the reaction of 2-methylthiophene with HNO₃ in acetic acid is 2-methyl-5-nitrothiophene.
