Answer:
The correct answer is C:
Kumho Tire Co. Ltd V. Daubert
Explanation:
In this case, the appellant (Daubert) has sued Kumho Tire Co. Ltd (the defendant) when 3 months prior the right rear tyre of his car exploded while the car was in motion killing a passenger and injuring others severely.
The appellant employed the services of an expert who had worked for 10 years with Michelin to give his opinion as having studied the attributes of the tire technology.
In a counter-argument, the defendant rather than dispute the opinion of the expert urged the court to exclude it as evidence because his methodology didn't conform to the requirements of the Law as given in Rule 702 of the Federal Rules of Evidence.
True to the defendants' position, the Law by the ruling in Daubert v Merrell Dow Pharmaceuticals required that for the opinion to count, it had to be scientifically correct. It was hence excluded as evidence in the case.
Cheers!
Answer:
The synthesis of p-chlorobenzenesulfonic acid with the reagents for each step and the structure of the monosubstituted intermediate compound is shown in the drawing below.
Explanation:
Benzenesulfonic acid is obtained from the sulfonation of benzene, using concentrated smoking sulfuric acid.
Chlorination of benzenesulfonic acid with chlorine without catalyst requires a polar solvent, such as acetic acid to obtain the selectivity in the position for and the ortho derivative in a low proportion.
It would be 36 because the atomic mass of carbon is 12
Answer:
Yield of CO₂ = 79.1 %
Explanation:
This is the balanced reaction:
CaCO₃ (s) + 2HCl (aq) → CO₂ (g) + CaCl₂ (aq) + H₂O (l)
As the hydrochloric acid is in excess, the limiting reactant is the CaCO₃.
Let's convert the mass to moles
10.9 g / 100.08 g/mol = 0.109 moles
Ratio is 1:1, so 0.109 moles of CaCO₃ will produce the same amount of CO₂.
Let's determine the mass
0.109 moles of CO₂ . 44 g/mol = 4.79 g
Now, we can determine the yield
(yeild produced / theoretical yield) . 100 =
(3.79 / 4.79) . 100 = 79.1%
