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,
The electronic configuration of Chlorine is,
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.
The chemical formula of the compound is KCl.

Answer:
You can fill 212 balloons.
Explanation:
First we <u>calculate the helium moles in the small cylinder</u>, using <em>PV=nRT:</em>
- P = 14300 kPa ⇒ 14300 * 0.009869 = 141.13 atm
- R = 0.082 atm·L·mol⁻¹·K⁻¹
- T = 25 °C ⇒ 25 + 273.16 = 298.16 K
141.13 atm * 2.20 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 298.16 K
Then we <u>calculate the number of moles that can fit in a single balloon</u>:
- 1.22 atm * 1.20 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 298.16 K
Finally we <u>divide the total number of available moles by the number of moles in a single balloon</u>:
- 12.70 mol / 0.0599 mol = 212.09
So the answer is that you can fill 212 balloons.
