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.

Explain:<br>(a) Ethanol should be rectified after distillation.

Maksim231197 [3]

Answer:

Ethanol (boiling point 78°C) and methanol (boiling point 65°C) are two miscible liquids. There is only a small difference in their boiling points. These two liquids are separated from their mixture by fractional ths distillation.

When vapours of the mixture pass through the fractionating column, repeated liquefaction and vapourisation take place. Subsequently, the vapours of low boiling methanol enter the condenser from the fractionating column, condense to liquid and get collected in the round bottomed flask first. Similarly, ethanol with higher boiling point can be collected later in another round bottomed flask.

A compound is made up of six carbon atoms, twelve hydrogen atoms, and six oxygen atoms. Which of the following chemical formulas

Mila [183]

<span>Since Carbon has a chemical name of "C," Hydrogen has "H" and Oxygen has O, we can start with the name "CHO". After this, the next task is to place the proper numbers next to the proper elements. In this case, the representation would be C(6)H(12)O(6), which would be the representation of the simple sugar glucose.</span>
