Lead oxide Carbon - Lead Carbon dioxide
Reactants
Products​

Answer 1

Sulfuric acid + Zinc = reactant

Zinc sulfate + hydrogen = product

Lead oxide + carbon = reactant

lead + carbondioxide = product

Step-by-step 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.
