Elements. Like oxygen and hydrogen and nitrogen, those are gases. Metals, like aluminum and iron. Metalloids, like sillicone and boron. Elements are the essential "elements"(WHAT!!!) of chemistry.
There is also a ton of math (really it's all about math), and calculations about charges (positive or negative) and balancing equations and moles(unit of mass for substances). But mostly its all math.
A Chemistry laboratory, to heat things.
The abbreviation for the tert-butyl group is -tBu. It is commonly used as a protecting group in organic chemistry to block reactive sites on molecules during chemical reactions.
Azide is a word that is commonly used in the chemistry world, more specifically, in organic chemistry. It is a proponent used in air bags (which are found in vehicles).
In chemistry, the term "en" signifies ethylenediamine, which is a compound commonly used as a ligand in coordination complexes.
milk of magnesia etc
An Erlenmeyer Flask is commonly used for chemistry experiements.
Kilometer = 1000 meter, a part of the SI units. However, it is a large distance, which would not normally be used in chemistry. A kilometer is roughly the distance you can walk in 10 minutes.
The symbol "ug" in chemistry stands for microgram, which is a unit of measurement equal to one millionth of a gram. It is commonly used in scientific measurements to express very small amounts of substances, such as in pharmaceuticals or environmental studies.
A green-top tube containing lithium heparin or a red-top tube without anticoagulant are commonly used for collecting blood samples for a chemistry profile.
The "I" in chemistry probably refers to the element iodine.
The most commonly used apparatus used in chemistry labs are beakers, round-bottomed flasks, glass bottles, Erlenmeyer flasks and wash bottles. Some of the other most used apparatuses used are microscopes.
The most commonly used apparatus in chemical lab. is a Test tube, every chemical or its chemical properties are checked with the help of test tube.
