In the expression 3H20, the 3 is a , while the 2 is a . A) coefficient: superscript B) coefficient: subscript C) superscript: subscript D) superscript: coefficient

The correct answer is  A) coefficient: superscript.

  In general:

2 is the coefficient of B, and 3 is the subscript of B.

 So, by comparing  with the given molecule,

3 = coefficient and 2 = subscript

Hence , the correct option is A.
