Which clue can be used to identify a chemical reaction as a replacement reaction? The reaction has two reactants with ions that seem to switch places. The reaction has a single reactant that changes into two or more products. The reaction involves oxygen reacting with a hydrocarbon and giving off heat. The reaction involves a single product forming from two or more reactants.

Answer 2

Explanation:

I think that it is displacement reaction.

There will be two metals where more reactive metal will take place of less reactive metal.

If the metal is less reactive then no reaction will take place.

for example: -

Fe + $CuSO_{4}$ → FeS$O_{4}$ + Cu

But if

Cu + $FeSO_{4}$→ No Reaction
