Hello!!!
what exactly are you wanting to know? It isn’t clear from your question. Please advise and I will answer it for you ASAP. I think I know what you are wanting but I don’t want to assume.... thank you
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.
The best and most correct answer among the choices provided by the question is the second choice.
