Define Chemistry - ansWer-the study of the composition, properties, and interactions of
matter.
Define Matter - ansWer-Anything that has mass and occupies space
Define Scientific method - ansWer-path of discovery that leads from question and
observation to law or hypothesis to theory, combined with experimental verification of
the hypothesis and any necessary modification of the theory
physical change - ansWer-does not affect the chemical makeup of a substance
chemical change - ansWer-change in chemical makeup of a substance
define matter: - ansWer-is defined as anything that occupies space and has mass, and
it is all around us.
Identify the three common states of matter - ansWer-solid , liquid, and gasses
describe waters state of matter - ansWer-A liquid flows and takes the shape of a
container, except that it forms a flat or slightly curved upper surface when acted upon by
gravity. (In zero gravity, liquids assume a spherical shape.)
describe solid state of matter - ansWer-is rigid and possesses a definite shape.
, describe gasses state of matter - ansWer-A gas takes both the shape and volume of its
container.
Classify matter as an element - ansWer-Pure substances that cannot be broken down
into simpler substances by chemical changes are called elements.
Classify matter as an compound - ansWer-Pure substances that can be broken down by
chemical changes are called compounds.
Classify matter as an homogenous mixture - ansWer-A homogeneous mixture, also
called a solution, exhibits a uniform composition and appears visually the same
throughout. (Gatorade)
Classify matter as an heterogenous mixture - ansWer-A mixture with a composition that
varies from point to point is called a heterogeneous mixture. for example: Oil and vinegar
salad dressing is a heterogeneous mixture because its composition is not uniform
throughout.
Classify matter as a mixture - ansWer-A mixture is composed of two or more types of
matter that can be present in varying amounts and can be separated by physical
changes, such as evaporation (you will learn more about this later).
the law of conservation of matter is and how it relates to the classifications of matter -
ansWer-The law of conservation of matter summarizes many scientific observations
about matter: It states that there is no detectable change in the total quantity of matter
present when matter converts from one type to another (a chemical change) or changes
among solid, liquid, or gaseous states (a physical change).
Classify whether N2 is a element, compound, pure substance, homogenous mixture,
heterogeneous mixture, or a solution - ansWer-Element and a pure substance
Classify whether O2 is a element, compound, pure substance, homogenous mixture,
heterogeneous mixture, or a solution - ansWer-element and pure substance
