Intro to Chemistry
Classification of Matter
States of Matter
Scientific Method
Laws, Theories and Models
100
The study of all substances and the changes that they undergo.
What is Chemistry?
100
anything that has mass and takes up space.
What is matter?
100
Solid, Liquid and Gas.
What are the states of Matter?
100
a logical approach to solving problems by observing and collecting data, formulating hypothesis, testing hypothesis, and formulating theories supported by data.
What is the scientific method?
100
observations that explain things but do not describe them. No exceptions have been found.
What is a law?
200
When running a lot your body goes into an oxygen debt were lactic acid is produced as a byproduct. This is ______ chemistry.
What is biochemistry?
200
extremely small building blocks of matter.
What are atoms?
200
In one change the original substance still exists; it has only changed in form. In the other change a new substance is produced. Energy changes always accompany this type of changes.
What are Physical and Chemical changes?
200
State the problem, hypothesis, experimentation, analysis, conclusion and communication.
What are the main steps of the scientific method?
200
summarizes a hypothesis which has been tested various times. May be disproven.
What is a theory?
300
Basic, Applied and Technological.
What types of research are there?
300
same atoms that cannot be decomposed into another substance.
What are elements made up of?
300
This type of property is observed with the senses and can be determined without destroying the objet. The other type of property indicated how the substance reacts with something else. Original Substance is fundamentally changed.
What is a Physical and Chemical property?
300
The variable you change in an experiment and the variable you observe or measure.
What is independent and dependent variable?
300
Representation designed to show a structure or concept.
What is a model?
400
Biochemistry
What type of Chemistry would the Study of photosynthesis in plants be?
400
a combination of two or more atoms (same or different) that are covalently bonded.
What is a molecule?
400
My shoes are red. This is an example of ________ property.
What are intensive propertied?
400
The group that will contain a changed element. The group that is not exposed to the independent variable.
What is experimental and control group?
400
Conceptual, Geometrical and Mathematical.
What types of models are there?
500
Applied Research
What type of research would be that of a pharmaceutical company exploring a disease that will maximize efficiency in medicine.
500
One is a combination that includes one or more substances and it is physically combined. The other has the same particles and could be chemically combined.
What is the difference between a mixture and a pure substance?
500
Properties that depend on the size of the sample involved.
What are extensive properties?
500
Factors that will be maintained the same in all trials of an experiment.
What are constant factors?
500
Changes or manipulated with relative ease.
Models may be ______ or __________ with _______ ease.
