A. Ca(OH)₂ → CaO + H₂O is a decomposition reaction

B. 4K + O₂ → 2K₂O is a synthesis reaction.

The correct answer to the question is Option (D) A is a decomposition reaction, and B is a synthesis reaction.

  • A decomposition reaction is a reaction in which a large compound is broken into two or more products for example:

XY —> X + Y

  • A synthesis reaction is a reaction in which two or more substances combine to produce a single product. For example

C + D —> CD

With the above information in mind, we conclude that:

A. Ca(OH)₂ → CaO + H₂O is a decomposition reaction

B. 4K + O₂ → 2K₂O is a synthesis reaction.

The correct answer to the question is Option (D) A is a decomposition reaction, and B is a synthesis reaction.
