Chemical Reactions
... In a synthesis reaction two or more substances combine to form a more complex substance. A decomposition reaction is the opposite of synthesis and breaks down a compound into two or more substances. In a single replacement reaction, one substance in a compound is replaced by another, more active, su ...
