To balance the chemical equation given:
\[
\text{?} + \text{H}_2\text{SO}_4 \rightarrow \text{KSO}_4 + \text{H}_2
\]
we need to identify the unknown reactant that can react with sulfuric acid (H₂SO₄) to produce potassium sulfate (KSO₄) and hydrogen gas (H₂).
The most likely reactant is potassium (K), as it can react with sulfuric acid.
Thus, if we use potassium as the reactant, the balanced equation can be written as:
\[
2 \text{K} + \text{H}_2\text{SO}_4 \rightarrow \text{K}_2\text{SO}_4 + \text{H}_2
\]
However, note that for every two moles of potassium, one mole of sulfuric acid will yield one mole of potassium sulfate and one mole of hydrogen gas.
So the equation involves:
Reactants: \(2 \text{K}\) and \( \text{H}_2\text{SO}_4 \)
Products: \( \text{K}_2\text{SO}_4 \) and \( \text{H}_2 \)
This provides a full reaction:
\[
2 \text{K} + \text{H}_2\text{SO}_4 \rightarrow \text{K}_2\text{SO}_4 + \text{H}_2
\]
\[
\text{?} + \text{H}_2\text{SO}_4 \rightarrow \text{KSO}_4 + \text{H}_2
