Final answer:

Alchemy was a precursor to modern Chemistry, focusing on mysticism and the transmutation of materials, while Chemistry is the empirical and systematic study of matter's properties and transformations. This evolution marked a shift from secrecy and speculation to openness and scientific rigor.

Explanation:

The difference between Chemistry and Alchemy lies in their approaches, goals, and methodologies. Alchemy, an ancestor to modern chemistry, was an ancient practice that combined elements of mysticism, philosophy, and early chemical understanding. Alchemists aimed to transmute common metals into valuable gold and sought the elixir of life, believing in the possibility of purification and perfection of certain substances. The work in alchemy was characterized by secrecy, as the knowledge gained was often not shared broadly and sometimes shrouded in allegory or symbolism.

As time progressed, especially with the end of the Middle Ages, alchemy gave way to the more empirical and systematic study of matter known as chemistry. Chemistry is the science concerned with the properties, composition, and transformation of matter. It is a discipline that focuses on understanding the elements, compounds, and reactions that constitute the material world. Significant figures such as John Dalton and Amedeo Avogadro contributed to establishing foundational principles like atomic theory and Avogadro's number, respectively, enhancing the scientific nature and rigor of the field.

Today, chemistry is a highly methodical science that values the sharing and verification of findings, as exemplified by scientists like Alma Levant Hayden, who exposed fraudulent medical claims through her scientific approach. The progress from alchemy to chemistry represents a significant transition from mysticism and speculation to a structured and evidence-based methodology.

Answer:

The difference between alchemy and modern chemistry is alchemy is based on a mystic, supernatural view of reality, whereas chemistry assumes reality is basically natural.
