In the presence of an acid catalyst, cyclohexanol (100.16 g/mol) is dehydrated to give cyclohexene (82.14 g/mol) and water. Reaction scheme illustrating the dehydration of cyclohexanol in the prescence of acid catalyst to cylcohexene and water. A dehydration reaction starting with 3.0 g cyclohexanol produces 1.9 g cyclohexene. Calculate the theoretical yield for this reaction. Report your answer with two significant figures.

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.
