According to molecular orbital theory,  regions of  wave function with highest probability of finding electrons are areas with constructive interference.
An electron is a negatively charged subatomic particle that can exist either free or bound to an atom (not bound). A bound electron is one of the three primary types of particles that make up an atom, along with protons and neutrons. Protons, neutrons, and electrons combined make up the atom's nucleus. A proton's positive charge balances an electron's negative charge. When an atom has an equal number of protons and electrons, it is said to be in a neutral state. Electrons are distinct from other particles in a number of ways. They have a much lower mass, are found outside the nucleus, and exhibit both wave- and particle-like characteristics. The electron is a basic particle.

Answer:
Nitrogen fixation is a chemical process by which molecular nitrogen in the air is converted into ammonia or related nitrogenous compounds in soil or aquatic systems. Atmospheric nitrogen is molecular dinitrogen, a relatively nonreactive molecule that is metabolically useless to all but a few microorganisms.

<h3><u>Answer</u>;</h3>
 ≈ 4.95 g/L
<h3><u>Explanation;</u></h3>
The molar mass of KCl = 74.5 g/mole 
Therefore; 0.140 moles will be equivalent to ;
  = 0.140 moles × 74.5 g/mole
  = 10.43 g 
Concentration in g/L 
    = mass in g/volume in L
    = 10.43/2.1 
    =  4.9667
<h3>   <u> ≈ 4.95 g/L</u></h3>
 
        
             
        
        
        
Barium chloride and lithium sulfate are mixed, barium sulfate and lithium chloride are formed. Barium sulfate is obtained as a white precipitate and lithium chloride as an aqueous solution.
