Answer:
The goal of the alchemists, who practiced from 400-1400 AD, was to transmute common elements (like lead) into gold. The alchemists used symbols to identify elements, and made many important discoveries which led to the development of the modern science of chemistry.
Explanation:
Alchemists were contracted by the elite for practical purposes related to mining, medical services, and the production of chemicals, medicines, metals, and gemstones. Entrepreneurial opportunities were common for the alchemists of Renaissance Europe.
Alchemy was based on the belief that there are four basic elements in nature: air, fire, water and earth. Alchemy is an ancient practice shrouded in mystery and secrecy. Its practitioners mainly sought to turn lead into gold, a quest that has captured the imaginations of people for thousands of years
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. That makes a huge difference, and chemistry would never have gotten very far if it had stuck with the old metaphysics.
Despite these connotations of the mythic and mystical, alchemical practice played an important role in the evolution of modern science to discover the relationship of humans to the cosmos and use that understanding to improve the human spirit. Alchemy was scientific but it was also a spiritual tradition.

Answer : The mass of carbon and oxygen produced is 8.83 g and 23.6 g respectively.
Explanation :
Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
The balanced chemical reaction will be,
As we are given:
According to the law of conservation of mass,
Total mass of 
= Mass of 
+ Mass of C
Total mass of = 2.67 + 1 = 3.67 g
Now we have to calculate the mass of and C.
and,
Therefore, the mass of carbon and oxygen produced is 8.83 g and 23.6 g respectively.
The reaction has had a heat that is enthalpy of -22 kJ/mol. The exothermic process has been signaled by the negative sign.
The amount of energy that the system absorbs or releases to create the products is described as the heat of reaction.
The source of the reaction's heat is
H is equal to 3(413 Kj/mol) + 358 Kj/mol + 467 Kj/mol + 1070 Kj/mol = 3134 Kj/mol.
H prod equals 3(413 kj/mol) plus 347 kj/mol plus 358 kj/mol plus 467 kj/mol plus 745 kj/mol, or 3156 kj/mol.
H=3134 kj/mol - 3156 kj/mol = -22 Kj/mol
Negative findings point to an exothermic response.
A chemical process known as an exothermic reaction releases energy in the form of heat or light.
