Physical science - Chemical substances

Chemistry Hypothesis

Predicts how changes in one variable will affect another such as temp changes affecting reaction rates

Mass

A measure of the amount of matter in an object

Pure Chemistry

A study concerned with a greater understanding of the theories behind how matter changes with chemical reactions

Applied Chemistry

Refers to the branch of chemistry which focuses on practical applications of chemistry (i.e.: medicinal, manufacturing, etc.)

Conclusion

A short paragraph that discusses the overall results of an chemical experimental procedure

Control Variable

Any factor that is controlled/held constant in a chemical experiment

Dependent Variable

The outcome or response measured in an experiment

Experimental Chemistry

Often referred to as bench chemistry, is the study of chemical reactions, properties, structures, and theories through practical, hands-on experimentation

Independent Variable

The factor that is changed or manipulated during an experiment.

Matter

Anything that has mass and volume/takes up space

Molecular Model

A physical model of an atomic system that represents molecules and their processes.

Qualitative Data

Refers to non-numerical information that describes characteristics or qualities(i.e. smell, appearance, etc.)

Quantitative Data

Refers to numerical information that can be measured and expressed mathematically(i.e. mass, volume, temp)

Scientific Laws

Laws of chemistry are statement based on repeated experiments or observations, that describe or predict a range of natural phenomena

Scientific Method

Chemistry is a study that is based on observation and experimentation. Performing chemistry involves attempting to answer questions and explain observations in terms of the laws and theories of chemistry, using procedures that are accepted by the scientific method.

Chemical Technology

The study of technology related to chemistry. Takes chemistry beyond the laboratory and into the industrial world

Theoretical Chemistry

Focuses on the mathematical and abstract aspects of chemistry

Weight

crucial in stoichiometry for calculating reactants and products in chemical reactions. measured in grams for small quantities

Chemical Substances

A unique form of matter with constant chemical composition and characteristic properties. Takes the form of a single element or chemical compounds.
