Question

A chemical change in which a single compound breaks down into two or more products is which of the following?

Select one:
a. Decomposition.
b. Double displacement.
c. Single displacement.
d. Synthesis.​

Answer 1

Answer:

a. Decomposition.

Explanation:

A combination reaction is a reaction where two or more elements or compounds combine to form a single compound. Such reactions may be represented by equations of the following form: X + Y ⇒ XY.

• Decomposition reactions are a type of chemical reaction that involves breaking down a compound into smaller compounds or individual elements.
• A single-displacement reaction, also known as a single-replacement reaction, is a reaction by which one element replaces other element in a compound.
• A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (action) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.

Hence, the answer is a decomposition reaction.
