Chemistry is a Physical Science
A property of matter that can be observed without changing the material.
What is a physical property?
A measurement of the amount of matter in any physical quantity.
What is mass?
Comprising the largest section of the Periodic Table, these materials are malleable.
What are the metals?
The System International (SI) unit for length.
What is the meter?
In mathematics, when combining powers in this way, one must be sure the base and the exponents are the same. For example, base 10 in scientific notation.
What are the addition and subtraction rules for exponents?
Characteristics of materials dependent on the amount of substance present including volume and amount of energy.
What are extensive properties?
A material formed by chemical means that can be broken down into component parts.
What is a compound?
Considering the periodic table, from one end to the other, the members of any one of these series become more different from each other the further they are apart.
What is a period?
A base unit of the System International (SI) that in 2019 underwent a change in its standard from a physical prototype to a calculated standard. It is also the only base unit that uses a prefix.
What is the kilogram (kg).
Zeros at the end of a number and to the right of a decimal point are significant. For example, 85.00g has 4 significant digits.
What is rule 3 for determining significant zeros?
A discipline in which the practitioner identifies materials for customers.
What is analytical chemistry?
A change in a material's overall atomic organization that is considered physical rather than chemical.
What is a change of state?
Considering the Periodic Table, the members of any given one of these series are similar in chemical attributes.
What is a group or family?
What is density (D)?
What is percent error?
A scientific effort expended to explore the nature of phenomena.
What is basic research?
This concoction is composed of more than one type of matter. All its components retain their original identities.
What is a mixture?
Materials with dull or no luster and varied hardness and brittleness. Also known as semiconductors.
What are metalloids?
Exactly 12 grams of Carbon-12 is used as the standard for counting out the number of particles of any pure substance equal to this amount.
What is a mole (mol)?
A relationship between variables in which their calculated ratio always gives a constant number no matter how they change.
What is a direct proportion?
No matter the sample size, a specific substance will always exhibit these.
What are intensive properties?
This class of materials includes complex particles but its members exhibit unchanging properties no matter how small the sample size.
What is a pure substance?
A group of non-metals with almost no reactivity with any other substance.
What are the noble gases?
A mathematical entity with infinite significance, perfect accuracy and perfect precision.
What is a conversion factor?
A technique used to transform quantities into units that are equivalent in order to make a calculation possible.
What is dimensional analysis?
