Elemental boron can be formed by reaction of boron trichloride with hydrogen.

A well-known scientist testifies that she believes a piece of evidence is accepted by science. The judge rules that the evidence

notsponge [240]

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!

Liquid A and liquid B form a solution that behaves ideally according to Raoult's law. The vapor pressures of the pure substances

Rama09 [41]

Answer:

Vapor pressure of solution → 151.1 Torr

Option 2.

Explanation:

Raoult's Law is relationed to colligative property about vapor pressure. A determined solute, can make, the vapor pressure of solution decreases.

ΔP = P° . Xm

where Xm is the mole fraction of solute, P° (vapor pressure of pure solvent)

and ΔP = Vapor pressure of pure solvent - Vapor pressure of solution.

In order to determine the vapor pressure of solution, we need to determine, the vapor pressure of B and A in the solution

B's pressure = P° B . Xm

When we add A to B, A works as the solute and B, as the solvent.

Vapor pressure of pure B is 135 torr. (P° B)

In order to determine, the Xm, we use the moles of A and B

Xm = 5.3 mol of B / (1.28 + 5.3) → 0.806

B's pressure = 135 Torr . 0.806 → 108.81 Torr

If mole fraction of B is 0.806, mole fraction for A (solute) will be (1 - 0.806)

A's pressure = 218 Torr . 0.194 → 42.3 Torr

Vapor pressure of solution is sum of vapor pressures of solute + solvent.

Vapor pressure of solution = 42.3 Torr + 108.81 Torr → 151.1 Torr

What best explains the observed trend in atomic radii going down the periodic table

HELP PLEASE I WILL GIVE BRAINLIEST PLEASE HELP ME

Sidana [21]

Answer:

The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction.

For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.

Another example, solar panels don't create solar energy. They harness energy from the sun and transform it into another type of energy (electricity).
