Explanation: A neutral compound is to be formed to get a stable compound. The charges have to be balanced , thus the valencies of ions are exchanged and the neutral compounds result.
These all are ionic compounds which result by complete transfer of electrons from metals to non metals.

Answer: Volume of the gas at STP is 22.53 L.
Explanation:
Given : Volume = 125 mL (as 1 mL = 0.001 L) = 0.125 L
Temperature =
Pressure =
According to the ideal gas equation, the volume of given nitrogen gas is calculated as follows.
PV = nRT
where,
P = pressure
V = volume
n = number of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Substitute the values into above formula as follows.
Hence, volume of the gas at STP is 22.53 L.
There’s no choices to pick from
