Answer:

Option A. 4mol/0.800Kg

Explanation:

Data obtained from the question include:

Mole of solute = 4 moles

Mass of water = 0.800Kg

Molality =.?

Molality of a solution is simply defined as the mole of solute per unit kilogram of solvent. Mathematically, it is expressed as:

Molarity = mole of solute / Kg of solvent

With the above formula, we can obtain the molality of KCl solution as follow:

Molality = 4mol/0.800Kg

3241004551 [841]

Potassium is not found free in nature but is found in the form of potash. Potash is the ore of potassium and this ore is mined from deep down the earth or can sometimes be found on the surface. Potash was mostly formed as sea water receded and left deposits.

Potash is usually in the form of potassium salts such potassium chloride and potassium sulphate. The potash is mined then taken to the factory where it is crushed and purified by removing such impurities as clay.

The now purified potassium salts are subjected to a process called electrolysis where potassium metal is obtained from its salt.

Determine the electron-group arrangement, molecular shape, and ideal bond angle(s) for each of the following:

lubasha [3.4K]

Solution :

a). $SO_3$

This compound is known as sulfur trioxide.

The molecular shape of sulfur trioxide is trigonal planer.

And the bond angle is 120°.

b). $N_2O$

This compound is known as Nitrous oxide. Here, nitrogen is in the center. There is no lone pair around the nitrogen atom and it forms two sigma bonds with the other two atoms.

It is linear in shape.

The bond angle between them is 180°.

c). $CH_2Cl_{2}$

This compound is known as the Dichloromethane.

The molecular shape of the compound is tetrahedral.

The bond angles is 120°

An alkyne with the molecular formula C5H8 was reduced with H2 and Lindlar's catalyst. Hydroboration-oxidation of the resulting a

irinina [24]

Since the addition of the H2O in the last step of hydroboration is anti-Markovnikov, the starting material is 1-pentyne.

The addition of H2 to C5H8 yields an alkene when a Lindlar catalyst is used. Recall that the Lindlar catalysts poisons the process so that the addition do not go on to produce an alkane.

When hydroboration is carried out on the alkene, we are told that a primary alcohol was obtained. We must note that in the last step of hydroboration, water is added in an anti- Markovnikov manner to yield the primary alcohol. Hence, the starting material must be 1-pentyne as shown in the image attached.
