Question

Which of the following takes place during a double displacement reaction?

a complex substance breaks down into two or more simple substances

a single substance replaces another substance in a compound

two simple substances combine to form a new complex substance

parts of compounds switch places to form two new compounds

Answer 1

double displacement: parts of compounds switch places to form two new compounds

FYI
decomposition: a complex substance breaks down into two or more simple substances

Single displacement: a single substance replaces another substance in a compound

Synthesis: two simple substances combine to form a new complex substance

Answer 2

Answer: The correct answer is parts of compounds switch places to form two new compounds.

Step-by-step explanation:

Double displacement reaction is defined as the reaction in which exchange of ions takes place to form two different compounds.

Decomposition reaction is defined as the chemical reaction in which a larger molecule breaks down into two or more smaller molecules.

Single displacement reaction is defined as a reaction in which more reactive metal displaces a less reactive metal from its chemical reaction.

Synthesis reaction is defined as the chemical reaction in which two or more smaller molecules combine to form a single larger molecule.

Hence, the correct answer is parts of compounds switch places to form two new compounds.
