Answer:
physical properties
Explanation:
temperature, volume and colour are all physical properties
Answer:
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.
At room temperature, it is a solid state of matter. hope this helps, have an amazing day :)
