Answer : The molecule 
is a polar molecule.
Explanation :
Polar molecule : When the arrangement of the molecule is asymmetrical then the molecule is polar.
Non-polar molecule : When the arrangement of the molecule is symmetrical then the molecule is non-polar.
The given molecule is,
The electronegativities of oxygen and fluorine are different. The molecular geometry of is bent. As, Fluorine is more elctronegative than the oxygen. So, the arrows putting towards the more electronegative element i.e, fluorine. These arrows do not balance each other. Due to this, the asymmetrical arrangement of these bonds makes the molecule polar.
Hence, the given molecule is polar.
<span>A neutralization reaction is a reaction in which an acid and a base react in an aqueous solution to produce a salt and water. An example of a neutralization reaction is the reaction of sodium hydroxide and hydrogen chloride to form sodium chloride and water. Answer is C.</span>
Answer:
C
Explanation:
Reduction can be seen through addition (gaining) of electrons, addition of Hydrogen or removal of Oxygen
Mn7+ is reduced to Mn4+ by the addition of 3 electrons.
