Explain why alchemy is not as reliable as modern day science

Chemistry
1 answer:
Ksivusya [100]3 years ago
3 0

Answer:

Explanation:

Alchemy is the forerunner of modern chemistry practiced during the medieval times. Chemists of those times were known and called alchemists.

These chemists had a very shallow knowledge of chemistry but were able to produce a wide range of chemicals.

  • Alchemy predates the scientific method.
  • Modern science is investigative and relies on the precepts of detailed and methodical process.
  • Modern day chemistry is a vertiginous study with more depth.
  • It seeks to provide details into reasons why certain chemical matter exists as they are. Or how combinations in reactions takes place.
  • Alchemy does not follow the scientific method in its investigation

What is a closed container in relation to the law of conservation of matter
Brums [2.3K]
The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as system mass cannot change quantity if it is not added or removed. Hence, the quantity of mass is "conserved" over time.

What happens when a metal is reduced. Give an example of a metal being reduced
AlexFokin [52]

Answer:

The oxidation number of the metal decreases

2 Al  + Fe₂O₃ → Al₂O₃ + 2 FeO

The metal element iron, is reduced from Fe⁺³ in Fe₂O₃ to Fe⁺² in FeO

Explanation:

When an element gains electron, the element becomes reduced, hence when a metal is reduced, the metal gains electrons, which reduces the oxidation number of the metal

An example of a metal being reduced is;

2 Al  + Fe₂O₃ → Al₂O₃ + 2 FeO

In the above reaction, the iron (III) oxide is reduced to iron (II) oxide by aluminium metal.
