You’re answer is A. (Life Science)
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: 5.844 grams of NaCl needed to make solution.
Explanation:
<span>Determine the concentration of the ion solvent in solution (moles of solvent/Liter of solution) and then multiply by Avogadro's Number. That will give you the number of ionic atoms of a particular type in that solution.</span>
We first write the chemical equation:
2HgO → 2Hg + O₂
Next, we calculate the moles of HgO present:
moles = 3 / 216.59
moles = 0.014
Each mole of oxygen gas needs 2 moles of HgO to be produced.
Theoretical moles of oxygen gas produced = 0.014 / 2
= 0.007
Theoretical mass of oxygen = 0.007 x 32 = 0.224 grams
Percentage yield = actual yield / theoretical yield x 100
= 0.195 / 0.224 x 100
= 87.0%
