Is it possible to produce any desired molecule starting with its respective components (elements) and systematically bind them?
For example, water can be decomposed through electrolysis, the result of the process being O₂ and H₂.
Now, if the hydrogen and oxygen I stored are both in an enclosed space and exposed to a flame, the result will be a violent exothermic reaction (an explosion) AND water. So through this two processes I could decompose and recompose water. This phenomenon left me wondering...
Is it possible to compose any chemical compound if I have the necessary elements? Sodium cyanide is NaCN, so if I have some sodium, some carbon and some nitrogen, I should be able to (somehow) make sodium cyanide, right?
I know this is a vague and rather theoretical question, but I'd really appreciate some explanations.
I hope nobody considers this question is crackpottery...
Also, if anyone knows about one or more books regarding this topic, please let me know!

This is a dream and great idea of the first half of XIX century chemists - realized. Now, we do not spend time for synthesis of complicated compounds from elements.
