Flashcards in Chpt. 3, Elements and Properties Deck (17):
1

chemical properties

properties that describe whether something will undergo a particular chemical reaction; flammability is one example

2

physical properties

any property that is not a chemical property; examples include melting/boiling point, color, mass, and density

3

intensive properties

properties that don't depend on the amount of material present

4

extensive properties

properties that depend on the amount of material present

5

solids

the hard state of matter

6

liquids

the fluid-like and shapeless state of matter

7

gases

the gas-like state of matter that is shapeless, and that is usually not visible

8

plasmas

gases that have lost their electrons

9

chemical change

when one substance is changed into another by making or breaking chemical bonds

10

physical change

changes that occur when the form of something is changed

11

The Law of Conservation of Mass

states that the products of a chemical reaction will weigh the same as the reactants

12

heterogeneous mixture

a mixture in which not all elements are uniform

13

homogeneous mixture

mixtures in which things have mixed in a completely uniform fashion (also known as solutions)

14

methods to separate the elements of a mixture

filtering, distillation, crystallization (getting a crystal to solidify from a solution, using a variety of different means)

15

element

a pure substance that can only make one type of atom

16

compound

a pure substance that contains only one type of molecule

17

Law of Definite Composition

the relationship and ratios between the various component parts of a reaction will always be the same
