Write a balance equation for the following (if no reaction occurs, indicate "no reaction)ethyl alcohol+H2S04 @ 140c?

You have asked for the chemical equation for the reaction of ethyl alcohol (C2H5OH) and H2SO4 (sulfuric acid) at a high temperature (140 degrees C).  The OH group in ethyl alcohol is called the hydroxyl group.  The oxygen atom in the hydroxyl group is electronegative (meaning it attracts electrons) and therefore has a partial negative charge.  Sulfuric acid is a very strong acid and readily loses a proton (H+) which is electropositive.  The proton is attracted to the hydroxyl oxygen to form the charged species (OH2)+ which is an excellent leaving group (it forms water (H2O)).  Another hydroxyl group from a neighboring ethyl alcohol molecule can replace this leaving group to form a new carbon-oxygen bond and produce a molecule of diethyl ether (C2H5-O-C2H5).  The balanced overall chemical reaction is shown below:


2C2H5OH + H2SO4 --> C2H5-O-C2H5 + H2O + H2SO4

Is there a word/phrase for "unperformant"?

As a software engineer, I need to sometimes describe a piece of code as something that lacks performance or was not written with performance in mind. Example: This kind of coding style leads to unmaintainable and unperformant code. Based on my Google searches, this isn't a real word. What is the correct way to describe this? EDIT My usage of "performance" here is in regard to speed and efficiency. For example, the better the performance of code the faster the application runs. My question and example target the negative definition, which is in reference to preventing inefficient coding practices. Answer This kind of coding style leads to unmaintainable and unperformant code. In my opinion, reads more easily as: This coding style leads to unmaintainable and poorly performing code. The key to well-written documentation and reports lies in ease of understanding. Adding poorly understood words such as performant decreases that ease. In addressing the use of such a poorly ...

Is 'efficate' a word in English?

I routinely hear the word "efficate" being used. For example, "The most powerful way to efficate a change in the system is to participate." I do not find entries for this word in common English dictionaries, but I do not have an unabridged dictionary. I have checked the OED (I'm not sure if it is considered unabridged), and it has no entry for "efficate". It does have an entry for "efficiate", which is used in the same way. Wordnik has an entry for "efficate" with over 1800 hits, thus providing some evidence for the frequency of use. I personally like the word and find the meaning very clear and obvious when others use it. If it's not currently an "officially documented" word, perhaps its continued use will result in it being better documented.
