Question

here is a chemical formula:
(nh₄)₂co₃
how many atoms of hydrogen (h) are in this substance?
○ 2
○ 4
○ 6
○ 8

Explanation:

Step1: Analyze the sub - formula for hydrogen

In the formula \((NH_4)_2CO_3\), the part related to hydrogen is \(NH_4\). Inside \(NH_4\), the sub - script for \(H\) is \(4\).

Step2: Consider the multiplier for the \(NH_4\) group

The \(NH_4\) group is multiplied by \(2\) (because of the sub - script \(2\) outside the parentheses). So the total number of \(H\) atoms is \(4\times2\).

Answer:

\(8\)
