Question

5 multiple choice 2 points
how many hydrogen atoms are in (nh₄)₂o?
10
8
6
4

Explanation:

Step1: Analyze the formula

In the formula \((NH_4)_2O\), the subscript \(4\) indicates there are 4 hydrogen atoms in one \(NH_4\) group.

Step2: Consider the coefficient

The coefficient \(2\) outside the parentheses means there are 2 \(NH_4\) groups. So the total number of hydrogen atoms is \(4\times2 = 8\).

Answer:

8
