Identify the balanced chemical equation that represents a single displacement reaction. cf4 2br2 ⟶ cbr4 2f2 3h2so4 2al ⟶ al2(so4)3 3h2 3h2so4 2al ⟶ al2(so4)3 h2 cf4 br2 ⟶ ⟶ cbr4 f2

3H₂SO₄ + 2Al₂(SO₄)₃  → Al₂(SO₄)₃ + 3H₂

Explanation:

                           3H₂SO₄ + 2Al₂(SO₄)₃  → Al₂(SO₄)₃ + 3H₂

In this type of reaction, one substance is replacing another:

                      A + BC  →  AC + B

In a single displacement reaction, atoms replace one another based on the activity series. Elements that are higher in the activity series. Also, if the element that is to replace the other in a compound is more reactive the reaction will occur. If it is less reactive, there will be no reation.

In the first equation, fluorine is more reactive than bromine. Therefore, bromine cannot replace bromine.

In the second equation, the displacement is between hydrogen and aluminium. Hydrogen is lower in the activity series, this implies that aluminum will replace it.

if you're asking what comes out, it's steam.
