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.
I believe the correct answer is the first option. A reaction with two reactants that is held by ionic bonding would most likely switch places and this is called a replacement reaction. The products would be new substances with new set of properties.
