Areas of Chemistry
This branch of chemistry deals with the study of substances and processes that occur in living things. It often focuses on nutrition of animals and humans.
What is biochemistry?
Mass is the measure of matter a sample contains. It is not to be confused with this measurement which takes into consideration gravitational pull.
What is weight?
This is a type of unit in which two measurements are combined to get the final unit.
What are derived units?
This group of elements are known to be great conductors of heat and electricity.
What are metals?
This allows you to determine mathematically how accurate you were with your measurements and calculations.
This branch of chemistry deals largely with carbon containing compounds.
What is organic chemistry?
These properties can be observed without changing the identity of the given substance.
What are physical properties?
This number is indicative of the number of protons found in the nucleus of an atom.
The vertical columns in the periodic table.
What are groups?
The number below is reported in this format.
6.4 * 1025
What is scientific notation?
What is inorganic chemistry?
This state of matter is observed when a solid substance is heated to its melting point.
What is liquid state?
This number contains ______ significant figures.
87,000,000.0
This collection of elements are all members of group 18 on the periodic table and are known to be very stable.
What are the Noble gases?
This law states that a sample of a given chemical compound contains the same elements in exactly the same proportions by mass no matter the size or the source of the sample.
What is the Law of Definite Proportions?
In this branch of chemistry, we study the composition of different materials and have the capability to differentiate between substances that appear otherwise to be identical.
What is analytical chemistry?
When this occurs, substances combine and form an entirely new substance with its own properties.
What is a chemical reaction?
The name of the number that is a measurement of the amount of atoms in 12 grams of carbon 12.
What is Avogadro's number?
This is the weight of one mole of any given substance.
What is molar mass?
These forces are what hold the dense nucleus together.
What are nuclear forces?
We use math and computers to more accurately explain the behavior of different compounds in this branch of chemistry.
What is theoretical chemistry?
This state of matter is observed when a sample of matter is heated so much the atoms in the substance lose their electrons.
What is plasma?
When reporting an answer that requires calculation, you must give your answer with the degree of certainty of this measurement.
What is least precise measurement?
(or the measurement with the least amount of significant figures)
This refers to an element that has a different number of neutrons than protons in its nucleus.
What is an isotope?
Different isotopes of elements are found in nature at disproportionate rates. This refers to the weighted average of the atomic masses of all the isotopes for any given element.
What is average atomic mass?
