D. MgF₂
Explanation:
The compound that is held together by the electrostatic force between two ions is MgF₂.
Electrostatic force of attraction is exhibited primarily and only in ionic compounds.
In this type of bond;
- A metallic atom such as Mg will lose two of its valence electrons to form Mg²⁺
- Two non-metal ion that is highly electronegative such as "F" will gain the two electrons because they require an electron each to have a perfect octet.
- Two ions are now formed.
- In the vicinity of one another, they attract with an electrostatic force.
- This is why our answer is MgF₂.
- Electrostatic force occurs in ionic/electrovalent compounds

Answer:
The final Volume of the gas in the cylinder
= 196.84 
Explanation:
Given that the volume of a gas in a container varies inversely with the pressure on the gas.
⇒ P ∝ 
⇒ P V = constant
=
--------- (1)
Given that
= 17 
= 19 
= 220 
⇒ 
⇒
= 196.84 
The final Volume of the gas in the cylinder
= 196.84 
Answer
given,
Resistance of the circuit R = 5 Ω
Voltage in the circuit , V = 10 V
current in the Circuit, I = 2 A
All these elements are connected in series.
A series connection in an electric circuit is that the current pass through resistance is same but the potential drops in between them.
The circuit diagram is attached in the attachment below which shows the elements connection in series.
