Answer:</h3>
Single displacement reaction
<h3>
Explanation:</h3>
- Single replacement reaction is a type of reaction in which a reactive element displaces a less reactive element from its compound.
- The reaction given above; Al + H₂SO₄ → Al₂(SO₄)₃ + H₂ is a single replacement reaction.
- This is because Aluminium takes the place of hydrogen atoms in sulfuric acid to form aluminium sulfate and hydrogen gas.
- Double replacement reaction is where cations or anions are exchanged between two compounds to form new compounds.
- For example the reaction; NaCl(aq) + AgNO₃(aq) → NaNO₃(aq) + AgCl(aq) is a double displacement reaction.
Li because its charge is +1.
Variables hope that helps
Answer:CO2(g) will be formed at a faster rate in experiment 2 because more H+ particles can react per unit time
