Composition of Matter
a. __________________ - either an element or a compound.
i. When all the atoms in a substance are alike, the substance in an ________________.
ii. A ___________________ is a substance with two or more elements combined in a fixed
proportion.
b. Two or more substances that can be easily separated by physical means form a
_______________.
i. _________________________- mixture of different and easily distinguishable materials.
ii. _________________________- contains two or more gaseous, liquid, or solid substance
blended evenly; also called a _________________.
iii. ____________- heterogeneous mixture with larger particles that never settle; colloids
scatter light in the _______________________.
iv. A heterogeneous mixture containing a liquid in which visible particles settle is called a
_________________.
Properties of Matter
a. _____________________- characteristics of a material which can be observed without
changing the identity of the substance in the material; examples include __________________
______________________________________________________________________________
i. __________________- physical description of a substance
ii. __________________- how a substance acts; for example magnetism, viscosity, ductility
iii. Physical properties such as size and magnetism can be used to _____________________
mixtures.
b. ____________________- change in a substance’s size, shape, or state of matter.
i. Substance does not change __________________ when it undergoes a physical change.
ii. __________________ is a process for separating a mixture by evaporating a liquid and
condensing its vapor.
c. _________________________- characteristics of a substance indicating that it can change
chemically; for example __________________________________________
d. When one substance changes to another substance, a _________________________ has
occurred.
i. Some chemical changes are indicated by ___________________ change, smell, or
bubble formation.
ii. Other chemical changes can be used to _______________ such as metals from their
ores.
e. __________________ of Earth’s surface involves both physical and chemical changes.
i. _______________- big rocks split into smaller ones; streams carry rock particles from
on location to another.
ii. _______________- Chemical changes can occur in rocks when calcium carbonate in
limestone changes to calcium hydrogen carbonate due to acid rain.
f. Law of ______________________- mass of all substance present before a chemical change
equals the mass of all substances after the change.
