|
Studies and uses instruments and methods used to separate, identify, and quantify matter. |
Analytical Chemistry |
|
|
This field of chemistry covers chemical compounds that are not carbon-based. |
Inorganic Chemistry |
|
|
The branch of science concerned with the chemical and physicochemical processes and substances that occur within living organisms. |
Biochemistry |
|
|
The branch of chemistry concerned with the application of the techniques and theories of physics to the study of chemical systems. |
Physical Chemistry |
|
|
The chemistry of carbon compounds (other than simple salts such as carbonates, oxides, and carbides). |
Organic Chemistry |
|
|
The extent to which results agree with one another. In other words, it is a measure of consistency, and is usually evaluated in terms of the range or spread of results. |
Precision (second-to-last digits all match) |
|
|
The closeness of a result to the true value. This can be applied to a single measurement, but is more commonly applied to the mean value of several repeated measurements, or replicates. |
Accuracy |
|
|
A widely used floating-point system in which numbers are expressed as products consisting of a number between 1 and 10 multiplied by an appropriate power of 10 |
Scientific Notation (a x 10^b) |
|
|
What does Si units stand for? |
The international system of units |
|
|
Analysis using the fact that physical quantities added to or equated with each other must be expressed in terms of the same fundamental quantities (such as mass, length, or time) for inferences to be made about the relations between them. |
Dimensional Analysis |
|
|
A unit of measurement obtained by multiplication or division of the base units of a system without the introduction of numerical factors. |
Derived Units (km/h, m/s, g/L,...) |
|
|
In an experiment, their values are studied under the supposition or demand that they depend, by some law or rule, on the values of other variables. (Change in response to a change in another property.) |
Dependant Variable (Y-axis) |
|
|
A variable whose variation does not depend on that of another. |
Independent Variable (X-axis) |
|

|
Base unit for length/distance? |
(m) meter |
|
|
Base unit for mass? |
Technically (Kg) kilograms, but we use (g) grams in the course. |
|
|
Base unit for time? |
(s) seconds |
|
|
Base unit for electrical current? |
(A) ampere |
|
|
Base unit for temperature? |
(K) kelvin |
|
|
Base unit for the amount of a substance? |
(mol) mole |
|
|
Base unit for luminous intensity? |
(cd) candela |
|
|
A measure of the total kinetic energy? |
Heat |
|
|
A measure of the average kinetic energy od the molecules? |
Temperature |
|
|
Relating to, measuring, or measured by the quality of something rather than its quantity. |
Qualitative |
|
|
Relating to, measuring, or measured by the quantity of something rather than its quality. |
Quantitative |
|
|
The energy that comes from motion. |
Kinetic energy |
|
|
The energy due to position, composition, or arrangement. Also, it is the energy associated with forces of attraction and repulsion between objects. |
Potential energy |
|
|
Changes affecting the form of a chemical substance, but not its chemical composition. |
Physical change |
|
|
This occurs when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. |
Chemical change |
