Water will be a product in a dehydration reaction. For example, when copper sulfate hydrate is heated, the water of crystallization vaporizes, leaving behind copper sulfate anhydrate.
"They contain at least one double or triple bond" is true of saturated fatty acid chains. This extra bond is why they are called "saturated", because they had less ability to take on other bonds.
Answer:
A)11,460 years
Explanation:half of a radioactive element represent the time take for half of it's components to dissociate or disintegrate.
For carbonn14 that undergo an emmision to form a stable carbon 14,it moves thus
14C(1 part) ______14C(0.5 parts)_____14C(0.25parts)
i.e it undergo two radioactive decay which means two half lives .
Since each half life is 5780 years ,the age will be 2×half lives= 2×5780=11,460 years
