Question

how many atoms of hydrogen are on the reactant side of the balanced chemical listed below? 2h₂o → 2h₂ + o₂

Explanation:

Step1: Analyze the reactant formula

The reactant is \(2H_2O\). The coefficient is 2, and in each \(H_2O\) molecule, there are 2 hydrogen atoms.

Step2: Calculate the total hydrogen atoms

To find the total number of hydrogen atoms, multiply the coefficient of the molecule by the number of hydrogen atoms in one molecule. So, \(2\times2 = 4\).

Answer:

4
