Answer:
The temperature of the Nitrogen after throttling is 
Explanation:
From the question we are told that
The temperature is 
The pressure is 
The pressure after being 
Generally from the first law of thermodynamics we have that
Here 
is the change internal energy which is mathematically represented as
Here 
is the specific heat of the gas at constant pressure
is the change kinetic energy which is negligible
Q is the thermal energy which is Zero for an adiabatic process
W is the work done and the value is zero given that the gas was throttled adiabatically
So
=> 
=> 
=>
Catalysts are chemicals that speed up reactions without changing themselves at the conclusion of the process.
By reducing the reaction's activation energy, they accelerate the pace of the reaction. By offering a surface or an orientation, catalysts reduce the activation energy of a process. supplying a different mechanism (a set of procedures the reaction must follow) with lower activation energy. As a result, catalysts facilitate the formation of chemical bonds between atoms to create novel combinations and new compounds.

Answer:
- the central atom is usually the atom with the lowest subscript in the molecular formula and the atom that can form the most bonds. If all of the atoms usually form the same number of bonds, the least electronegative atom is usually the central atom.
- molecular shape (the shape that a single molecule has) is important in determining how the molecule interacts and reacts with other molecules. Molecular shape also influences the boiling point and melting point of molecules. If all molecules were linear then life as we know it would not exist.
Answer: The smallest bond angle in the molecule x-y-x is 
Explanation:
According to VSEPR theory , each atom in a molecule will achieve a geometry that minimizes the repulsion between electrons in the valence shell of that atom.
In the given compound 
, the number of electron pairs is 2 that means the hybridization will be 
and geometry of the molecule will be linear as there are two bond pairs .The bond angle for linear geometry is 180° which reduces the electron electron repulsions and maximise stability.
