    Sulfuric acid + Zinc = reactant

    Zinc sulfate + hydrogen = product

    Lead oxide + carbon = reactant

    lead + carbondioxide = product

    Explanation:

    Chemical equation:

    Sulfuric acid + Zinc → Zinc sulfate + hydrogen

    H₂SO₄ + Zn → ZnSO₄ + H₂

    In this reaction sulfuric acid and zinc react to produce the zinc sulfate and hydrogen. That's why sulfuric acid and zinc are reactant. While zinc sulfate and hydrogen are products.

    2nd reaction:

    Lead oxide + carbon → lead + carbondioxide

    2PbO + C → 2Pb + CO₂

    In this reaction Lead oxide and carbon react to produce the lead and carbondioxide. That's why Lead oxide and carbon are reactant. While lead and carbondioxide are products.
