1. Well, we all know that pV=nRT. Hence V=nRT/p
'n' represents the number of moles of the gas
p is the pressure
R is the molar gas constant
T is the temperature.
But number of molecules(N) =n*NA
2. Ammonia and excess chlorine react to produce nitrogen trichloride
NCl3 is an explosive liquid.
3.NaOH does not participate as flux. The Crude bauxite is dissolved in a concentrated solution of NaOH to separate the Al3+ from impurities
4. The main factor that determines the discharge of ions during electrolysis is the position of the ions in the electrochemical series. The factor of concentration is important only if the ions are located very close to each other in the series. In such cases, the ion in higher concentration is usually discharged preferentially
