What made alchemy unscientific in its practices

Chemistry
1 answer:

The answer is that they were were not based on evidence and experiment and that made alchemy unscientific in its practices.

Alchemy is an old practice that might be thought of as a forerunner of chemistry.

The term alchemy is derived from the Arabic al-kimiyya, which is derived from Greek. Alchemy's fundamental notions focus around the transformation of one substance into another, often transforming a basic metal like lead or iron into a "noble" metal like silver or gold

The alchemist's main ambitions were to find the Stone of Knowledge, the medium of Eternal Youth and Health, and metal transmutation.

To conclude with we can say Alchemy is based on magic and occultism rather than true investigation and facts. Many of the items in it have been utilised as fundamentals for certain chemistry, although the vast majority of them are wrong and inaccurate.

What is the most important clue that a chemical reaction is taking place?
Paul [167]
I will give you two clues just incase:

-Change in temperature-usually when a reaction takes place heat will be absorbed or released which result in a temperature change.-eg: put a piece of sodium in water. you will feel or observe that the temperature is increased


-Change in colour-Some times we see a colour change in the media when a reaction takes

How important each one is depends on what you are learning about a chemical reaction. Hope I helped!

Draw both major organic product(s) that are obtained when 4-chloro-2-methyltoluene is treated with sodium amide followed by trea
victus00 [196]

Answer:

I attached the answer as an image. I also drew in the two most acidic hydrogens.

Explanation:

This goes through the 'benzyne' intermediate, meaning it does an E2-looking reaction by expelling a leaving group (chloride) from the adjacent part of the ring using the amide as a strong base. The triple-bonded benzyne has absurd bond angle strain, and is vulnerable to a good nucleophile like an amide ion, and the resultant sp2 anion is then reprotonated by the acid. I didn't draw in the acid-base reaction in step one, or the spectator ion (sodium).

When we compare the two solids, we see that quartz is a crystalline solid with relatively long-range order and glass is amorphous solid with short range order and has a tendency to flow. When quartz is heated, it can be easily converted into glass.
