Fractional distillation is the most efficient technique to separate solid benzoic acid mixed with a volatile alkyl halide liquid components.

<h3>Fractional distillation :</h3>

Separating a mixture into its constituent parts, or fractions, is known as fractional distillation. Chemical compounds are separated by heating chemical mixtures to a temperature at which one or more fractions of the mixture evaporate. Distillation is used to fractionate.

Boiling a mixture of liquids results in vapors rising up a glass tube known as a "fractionating column," which is followed by separation. The fractionating column, which is placed between the flask holding the mixture and the "Y" adaptor, improves the separation of the liquids being distilled.

<h3>Uses of fractional distillation :</h3>

Alcohol purification, desalination, crude oil refinement, and the creation of liquefied gases from air are all applications of distillation.

Illusion [34]

Answer:

8.9 m/s^2

Explanation:

The period of a simple pendulum is given by the equation

T=2\pi \sqrt{\frac{L}{g}}

where

L is the lenght of the pendulum

g is the acceleration due to gravity at the location of the pendulum

We notice from the formula that the period of a pendulum does not depend on the mass of the system

In this problem:

-The pendulum comes back to the point of release exactly 2.4 seconds after the release. --> this means that the period of the pendulum is

T = 2.4 s

- The length of the pendulum is

L = 1.3 m

Re-arranging the equation for g, we can find the acceleration due to gravity on the planet:

g=(\frac{2\pi}{T})^2 L=(\frac{2\pi}{2.4})^2(1.3)=8.9 m/s^2

How much force does it take to accelerate a 2,000-kg car at 4 m/s
Leona [35]

Answer:

C. 8,000 N

Explanation:

<em>Newton's second law of motion</em> describes the relationship between an object's mass and the amount of force needed to accelerate it.  

This law can be expresses as F=ma,

where  

  • F -  force acting on an object
  • m-  the mass of an object  
  • a -  its acceleration

The more mass an object has, the more force you need to accelerate it. And the greater the force, the greater the object's acceleration.

<em>F = ma </em>

<em>   =2000×4 = 8,000 N</em>

The whale shark the largest of fish and can have the mass of three adult elephants. Suppose that a crane is whale shark into a t
Alona [7]

Answer:

Mass, m = 20000 kg

Explanation:

The force acting on the shark, F=2.5\times 10^4\ N

Acceleration of the shark, a = 1.25 m/s²

We need to find the mass of the Shark. The force acting on an object is given by :

F = ma

m is the shark's mass

So,

m=\dfrac{F}{a}\\\\m=\dfrac{2.5\times 10^4}{1.25}\\\\m=20000\ kg

So, the mass of the Shark is 20000 kg.

Which term defines the amount of mechanical work an engine can do per unit of heat energy it uses? A. specific heat B. conductiv
KengaRu [80]

Answer:

Efficiency

Explanation:

  • The amount of mechanical work an engine can do per unit of heat energy it uses is called its efficiency.
  • It is also defined as the output divided by the total electrical power consumed.
  • In terms of heat, efficiency of engine is given by :

\eta=1-\dfrac{Q_o}{Q_i}

Q_o\ and\ Q_i are output heat and input heat respectively.

Hence, the correct option is (d) "efficiency"
