Answer: Evaporation Condensation is used to seperate the parts of a mixture 
Explanation: This is because it is the first order of the distilation process
 
        
             
        
        
        
Answer:
 
1 kiloliter = 1,000,000 milliliters 
45 × 1,000,000 
45 KL = 45,000,000 ML
 
        
                    
             
        
        
        
Solid and liquid particles
        
             
        
        
        
Answer:
The correct answer to the following question will be "90.6 kJ/mol". 
Explanation:
The total reactant solution will be:

The produced energy will be:



The reaction will be:
⇒  
Going to look at just the amounts of reactions with the same concentrations, we notice that they're really comparable.  
Therefore, the moles generated by NaCl will indeed be:
=  
=  
=  
Now,
=  
=  
=  
 
        
             
        
        
        
we have to know the spin of valence electrons of carbon-14
There are four unpaired electron which are called as valence electron also.The spin of the four unpaired electron is either upfilled or down filled.
The ground state electronic configuration of C-atom is 1s²2s²2p² and one electron from 2s orbital gets excited to 2p orbital. The elctronic configuration in excited state is 1s²2s¹
.
The electron jumps because half-filled orbitals are more stable. Exchange energy is less than pairing energy.
