What is chemistry?

5000 BCE

the branch of science concerned with the substances of which matter is composed, the investigation of their properties and reactions, and the use of such reactions to form new substances.
the chemical composition and properties of a substance or body.
plural noun: chemistries
"the patient's blood chemistry was monitored regularly"

primitive times

4970 BCE

The first important chemical reaction that controlled human was fire. There remains dated around 500,000 years attest to the mastery of fire, at least since the time of Homo erectus ago.then it was the land air and water

time of antiquity.

2500 BCE

Since ancient times humans discovered the chemical as they handled various materials for their needs for food, shelter, clothing and defense. Al prinipio they used stones, and later discovered metals such as copper, tin, bronze and iron, with which manufactured tools and weapons of war, a time which is known as the Stone Age. In ancient times and knew some cosmetics (mostly they were toxic, but women unknowingly used as mercuio and arsenic) and drugs.

characters of chemistry.

1920 BCE

Allow them to change
The novel is a journey your characters take and they must grow. You can have your romance characters grow and change together as the story unfolds.
If your characters fight with each other, let them resolve their issue before the story ends. (unless it’s a series like Fifty Shades of Grey) This must to resolve all issue is for stand-alone novels.
Even so, at the end of the series the characters should have reconciled their differences if it is a romance novel.

phlogiston theory

1069 BCE

The phlogiston theory is a superseded scientific theory that postulated that a fire-like element called phlogiston is contained within combustible bodies and released during combustion.

iatrochemistry

17 BCE

iatrochemistry or yatroquímica is a historical branch of science that linked the chemical and medicine. Taking their bases in alchemy, iatrochemistry sought to find chemical and pathological processes in the human body physiological explanations, and provide treatment with substances.

alquimia

15 BCE

In the Greek it is where the etymological origin of the term is alchemy. Specifically we can determine that this is in the term chemia, which can be defined as "liquid mixture". Of that word it was broke which then create alchemy as such which was established by the Arabs who were the ones who created the term alkímya.

Chemistry is the study of the composition, structure, and properties of matter, the processes that matter undergoes, and the energy changes that accompany these processes. It deals with a material’s makeup, changes in a variety of temperatures, and many other things.
the matter is not created nor destroyed only changes form.

chemistry as a scientific activity

Dec 24, 1978

https://www.youtube.com/watch?v=TZRjc515KjY Chemistry can be fascinating for kids! These hands-on, visual chemistry activities spark the joy of learning for kids of any age. Adults can prepare with a simple list of materials and instructions and turn the fun over to the student. As they see chemistry principles come alive, they'll be asking for more simple experiment activities.
