A single replacement reaction is a reaction in which one element replaces a similar element within a compound. True False

True

Explanation:

In a single replacement reaction, one element is replacing a similar element within a given compound.

For example;

       A  + BC → AC + B

The replacement of a metallic ion in solution by a metal ion higher in the activity series than the metal in solution falls into this category of reactions.

The relative position of the two elements in the activity series provides the driving force for the single replacement reactions.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
