The loss of static energy as electric charges move off an object is called electric discharge.

Electric discharge can be defined as release and transmission of electricity through a medium in an applied electric field.

It results from the conducting path between two points of different electrical potential in the medium where the points are immersed.

10g of a non-volatile and non-dissociating solute is dissolved in 200g of benzene.

ehidna [41]

<u>Answer: </u>The molar mass of solute is 115 g/mol.

<u>Explanation:</u>

Elevation in the boiling point is defined as the difference between the boiling point of the solution and the boiling point of the pure solvent.

The expression for the calculation of elevation in boiling point is:

$\text{Boiling point of solution}-\text{boiling point of pure solvent}=i\times K_b\times m$

$\text{Boiling point of solution}-\text{Boiling point of pure solvent}=i\times K_f\times \frac{m_{solute}\times 1000}{M_{solute}\times w_{solvent}\text{(in g)}}$ ......(1)

where,

Boiling point of pure solvent (benzene) = $80.10^oC$

Boiling point of solution = $81.20^oC$

i = Vant Hoff factor = 1 (for non-electrolytes)

$K_b$ = Boiling point elevation constant = $2.53^oC/m$

$m_{solute}$ = Given mass of solute = 10 g

$M_{solute}$ = Molar mass of solute = ? g/mol

$w_{solvent}$ = Mass of solvent = 200 g

Putting values in equation 1, we get:

$81.20-80.10=1\times 2.53\times \frac{10\times 1000}{M_{solute}\times 200}\\\\M_{solute}=\frac{1\times 2.53\times 10\times 1000}{1.1\times 200}\\\\M_{solute}=115g/mol$

Hence, the molar mass of solute is 115 g/mol.

How many moles of ammonia can be produced when 2.50 moles of hydrogen react?

jeyben [28]

Answer:

5/3 moles

Explanation:

3.moles.of H2 gives 3 moles of NH3

so 2.5 moles gives 5/3 moles.

Note:Apply simple. concept of unitary method.

When sulfuric acid and potassium hydroxide neutralize each other to make water and potassium sulfate, how is water formed?

statuscvo [17]

It's formed by the hydrogen ion of the acid and the hydroxide of the base.

$H_{2} SO_{4} + 2KOH --\ \textgreater \ K_{2} SO_{4} + 2H_{2}O$
Sulfuric Acid + potassium superoxide --> Potassium Sulfate + Heavy Water

Hope this Helps :)
