Question

Which terms identify types of chemical reactions?

(1) decomposition and :sublimation

(2) decomposition and synthesis

(3) deposition and sublimation

(4) deposition and synthesis

Answer 1

The answer is decomposition and synthesis. A synthesis response is a reaction in which two or more constituents mix to make a new compound. When two elements mix in a synthesis reaction, the only outcome that can be completed is a binary compound while a decomposition reply is when a compound splits into its compounds or elements.
