Answer:

Fe + 3NaBr → FeBr₃ + 3Na

Explanation:

Single replacement:

It is the reaction in which one elements replace the other element in compound.

AB + C → AC + B

Chemical equation:

Fe + 3NaBr → FeBr₃ + 3Na

This chemical equation shows the single replacement reaction. Iron replace the sodium and react with bromine.

All other options are incorrect because,

Ca(OH)₂ + H₂SO₄ → CaSO₄ + 2H₂O

It is double replacement reaction.

CH₄ + 2O₂ → CO₂ + 2H₂O

This reaction equation shows combustion.

H₂O + CO₂ → H₂CO₃

This is synthesis reaction.
