100
Chemistry concerned with a greater understanding of the theories behind how matter is changing in chemical reactions
What is pure chemistry?
100
A systematic and logical approach to the acquisition of knowledge.
What is the Scientific method?
100
Matter that has a uniform and definite composition.
What is a pure substance?
100
A technique that separates solids from liquids in a heterogeneous mixture
What is filtration?
100
A substance that is present at the end of a chemical reaction
What is the product?
200
Chemistry that is directed toward a specific practical goal or application
What is applied chemistry
200
A testable conjecture that proposes an answer to the question.
What is a hypothesis?
200
A characteristic of a substance that can be observed or measured without changing the identity of the substance.
What is a physical property?
200
A method of separating a mixture based on differences in boiling points.
What is distillation?
200
Describes the ability of a substance to undergo a specific chemical change.
What is a chemical property?
300
The study of carbon-containing chemicals.
What is Organic chemistry
300
In an experiment this is the variable that is changed during an experiment.
What is an independent variable?
300
A change to a sample of matter in which some properties of the material change, but the identity of the matter does not.
What is a physical change?
300
A change that produces matter with a different composition.
What is a chemical change?
300
A process that occurs when one or more substances are changed into one or more new substances
What is a chemical reaction?
400
The study of chemicals that do not, in general, contain carbon.
What is Inorganic chemistry
400
A group that experiences the same conditions as the experimental groups with the exception of the variable that is being tested.
What is the control group?
400
A property of matter that depends only on the type of matter in a sample and not on the amount.
What is the intensive property?
400
A mixture in which the composition is not uniform throughout the mixture.
What is a heterogeneous mixture?
400
A substance that is present at the start of a chemical reaction.
What is a reactant?
500
The study of chemical processes that occur in living things.
What is biochemistry?
500
In an experiment the variable that is observed during an experiment.
What is the dependent variable?
500
A property that depends on the amount of matter in a sample.
What is the extensive property?
500
A mixture in which the composition is uniform throughout the mixture.
What is a homogeneous mixture?
500
A solid product that forms from a reaction and settles out of a liquid mixture.
What is a precipitate?
