Question

11/19 how many hydrogen atoms are in 4h₂o? 6 2 4 8

Explanation:

Step1: Analyze the formula \(4H_2O\)

In the chemical formula \(H_2O\), the subscript \(2\) indicates that each water molecule contains \(2\) hydrogen atoms.

Step2: Calculate total hydrogen atoms

We have \(4\) molecules of \(H_2O\). To find the total number of hydrogen atoms, we multiply the number of hydrogen atoms per molecule (\(2\)) by the number of molecules (\(4\)). So the calculation is \(2\times4 = 8\).

Answer:

8 (corresponding to the blue - colored option with the number 8)
