Answer:
The major product from this reaction is 4-bromobenzene diazonium chloride.
Explanation:
The reaction of p-bromoaniline with HNO2 and HCl produces diazonium salt. When primary aromatic amines are nitrosated with nitrous acid in the presence of a strong acid such as HCl, diazonium salts are frequently formed. The diazonium salts are a crucial step in the production of halides and azo compounds. The necessary reaction mechanism is depicted in the illustration in the diagram below.
Answer: The gray mice would immediately be eaten by the predators in the area and go extinct.
Explanation:
Natural selection is the differential survival of some members of the population of species which have better phenotypic advantage over others. Such members will survive and reproduce. According to the given situation, white mice were the choice of food for predators and the recessive trait of gray color of gray mice was favoring their survival as they may remain undetected by the predators. But the predators were able to detect the gray mice and changed their food preference from white to gray this way predators will consume all the gray mice and they may extinct in future as it is not possible to change the color of the fur from white to gray so quickly. The adaptation and passage of white trait among the members of the population will occur with a gradual change in successive generations of the population.
Answer:
They are generally found in mines
Dissolution and dissociation of aluminum chloride:
AlCl₃(s) → Al³⁺(aq) + 3Cl⁻(aq)
The cation of aluminum is hydrolyzed:
Al³⁺ + 2H₂O ⇄ AlOH²⁺ + H₃O⁺
AlOH²⁺ +2H₂O ⇄ Al(OH)₂⁺ + H₃O⁺
Al(OH)₂⁺ + 2H₂O ⇄ Al(OH)₃ + H₃O⁺
