Answer:
The answer to your question is: letter A.
Explanation:
A Covalent bond polar is between 2 non metals where one atom is bigger than the other one so the distribution of charges creates this polarity.
A. One atom attracts shared electrons more strongly than the other atom  This is the correct definition of bond polar, one element is bigger and stronger than the other element.
B. One atom has transferred its electrons completely to another atom  This definition is incorrect, it is the definition of ionic bonding.
C. A sea of electrons has been created between the elements  This definition is incorrect for the polar bond, it describes a metallic bonding.
D. Two atoms are sharing electrons with equal attraction This definition is incorrect for a polar bond, but is the correct definition for nonpolar bonding.
 
        
             
        
        
        
Is an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge. Static electricity is named in contrast with current electricity, which flows through wires or other conductors and transmits energy.[1]
        
             
        
        
        
Answer : The correct option is, 13.7 mole
Solution : Given,
Moles of  = 27.4 moles
 = 27.4 moles
The given balanced chemical reaction is,

From the balanced chemical reaction, we conclude that
As, 2 moles of  react with 1 moles of
 react with 1 moles of 
So, 27.4 moles of  react with
 react with  moles of
 moles of 
Therefore, the number of moles of oxygen  required are, 13.7 moles
 required are, 13.7 moles
