In the chemical reaction \(2H_2 + O_2 \rightarrow 2H_2O\), there are four hydrogen atoms (H) on the left side, coming from 2 molecules of \(H_2\).
On the right side, the product \(2H_2O\) contains 2 hydrogen atoms in each water molecule. Since there are 2 water molecules produced, the total number of hydrogen atoms on the right side is \(2 \times 2 = 4\).
Therefore, the number of hydrogen atoms present after the reaction is also 4.
The correct response is: **4**.
