Answer:
crust
Discuss with the whole class what the relative thicknesses of the layers are — that the inner core and outer core together form the thickest layer of the Earth and that the crust is by far the thinnest layer.

Answer:
fluoride ion with a charge of -1
Explanation:
If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1.
 
        
             
        
        
        
P =mgh
You have mass, g =9.8 m/s2 and height calculate the potential energy P 
 
        
             
        
        
        
Answer : The balanced reaction in acidic solution is,

Explanation :
The given partial equation is,

First we have to separate into half reaction. The two half reactions are:


Now we have to balance the half reactions in acidic medium, we get:
 ............(1)
       ............(1)
 ............(2)
     ............(2)
Now we have to balance the electrons of the half reactions. When we are multiplying the equation (1) by 2, we get
 ...........(3)
  ...........(3)
Now we have to add both the half reactions (2) and (3), we get the final balanced chemical reaction.
