Question

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

Answer 1

Answer:

B) coefficient: subscript

Explanation:

Given

$3H_2O$

Required

What does 3 and 2 represents

On a general term:

In $nA_m$

$n = The\ coefficient\ of\ A$

And

$m = The\ subscript\ of\ A$

So, by comparing $3H_2O$ with the general term, $nA_m$

$n = 3$

$m = 2$

Hence,

3 = coefficient and 2 = subscript
