The Different Branches of Chemistry
What is organic chemistry?
This is the thing that stays the same throughout the entire experiment.
What is the constant?
A quantity that includes both number and unit.
What is measurement?
Characteristics of a substance that can be observed or measured without changing the substance.
What is a physical property?
What is matter?
The study of matter and the processes of living organisms.
What is biochemistry?
This way of acquiring knowledge begins with an observation followed by a hypothesis, an experiment, an analysis, developing theories, and sharing your work with other scientists.
What is the scientific method?
M x 10n
What is scientific notation?
Describes the ability of a substance to undergo a specific chemical change.
What is a chemical property?
Examples of this include hydrogen (H), Helium (He), and Lithium (Li).
What is an element?
This branch of chemistry studies matter without the presence of carbon.
What is inorganic chemistry?
This is a standard for comparison in an experiment.
What is the control variable?
What is accuracy?
A change where properties of the material change, but the identiy doesn't.
What is a physical change?
This is a mixture that you can sometimes see through, but is completley uniform in its composition.
What is a homogeneous mixture?
What is physical chemistry?
This is the thing that you change in an experiment.
What is the independent variable?
The difference between the accepted value and your measuremen.
What is error?
A change that produces matter with a different composition.
This mixture is made up of colloids and suspensions, and is not a uniform substance.
What is a heterogeneous mixture?
The branch of chemistry that studies the components and composition of matter.
What is analytical chemistry?
This is the thing that changes because of what you did.
What is the dependent variable?
How close a set of measurments are to eachother.
What is precision?
Filltration, distillation, crystallization, and chromatography are examples of...
What is seperation of mixtures?
This is a subcategory of physical properties where the property depends on the amound of a substance.
What is an extensive property?
