Question: how are the waters of hydration eliminated from a hydrated compound

title: Hydrate
text: In organic chemistry , a hydrate is a compound formed by the addition of water or its elements to another molecule . For example : ethanol , CH -- CH -- OH , is the product of the hydration reaction of ethene , CH = CH , formed by the addition of H to one C and OH to the other C , and so can be considered as the hydrate of ethene . A molecule of water may be eliminated , for example by the action of sulfuric acid . Another example is chloral hydrate , CCl -- CH ( OH ) , which can be formed by reaction of water with chloral , CCl -- CH =O . 

Answer: answer: In organic chemistry , a hydrate is a compound formed by the addition of water. A molecule of water may be eliminated , for example by the action of sulfuric acid.
answer: Adding water or its elements to another molecule results in a hydration water, the molecule of which can be eliminated by the action of sulfuric acid.
