Question

which of the following shows the correct atom count for sulfur on the reactant side of the equation? 3h₂so₄ + 2fe → fe₂(so₄)₃ + 3h₂ 3 atoms of sulfur on the reactant side 2 atoms of sulfur on the reactant side 1 sulfur atom on the reactant side 4 atoms of sulfur on the reactant side

Explanation:

Step1: Identify reactant side

The reactant - side of the equation is $3H_2SO_4 + 2Fe$.

Step2: Analyze sulfur atoms in reactant

In $H_2SO_4$, there is 1 sulfur atom per molecule. The coefficient of $H_2SO_4$ is 3. So the number of sulfur atoms is $3\times1 = 3$.

Answer:

3 atoms of sulfur on the reactant side
