Answer:

Increases

Explanation:

As the number of carbons in the hydrocarbon increases, the boiling point of increases and volatility reduces.

The increasing number of carbon atoms increases the molecular mass and this will eventually lead to a higher boiling point.

With increasing chain length, hydrocarbons tends towards liquid and solid phases.
This increase leads to a greater intermolecular interaction in the compound.
Intermolecular forces determines the boiling point of hydrocarbons.
This is why gasoline is easily combusted compared to lubricant oil.

What type of compound is created when potassium and chlorine combine explain how they combine and write the chemical formula. Ne

Elodia [21]

Answer : Ionic compound is created when potassium and chlorine combine. The chemical formula of the compound is KCl.

Explanation :

When potassium and chlorine combine then the type of compound created is Ionic compound.

Ionic compound : These are those compounds which are made of a metal element and non-metal element. Salts are ionic compound which consists of a positive and negative ions.

The electronic configuration of Potassium is,

$1s^22s^22p^63s^23p^64s^1$

The electronic configuration of Chlorine is,

$1s^22s^22p^63s^23p^5$

From this we conclude that the potassium atom is a metal which has 1 electron in their valence shell and chlorine atom is a non-metal which has 7 electrons in their valence shell. For the complete octet, chlorine atom needs only 1 electron which it receives from the potassium atom.

During this process, potassium atom will loses 1 electron and acquire positive charge and chlorine atom will gain 1 electron from potassium atom and acquire negative charge.

$K^++Cl^-\rightarrow KCl$

The chemical formula of the compound is KCl.
