Transcript of Copy of Chemistry - chp 2 Matter and Change

Properties to describe matter:
extensive properties: depend on the amount of matter
intensive properties do not depend on the amount of matter - [always the same wether there's a little or a lot]
boiling point
color Physical Properties of Matter:
the condition observed/measured
luster Physical States of Matter
plasma Matter and Change Physical Changes:
properties change-
not the materials ****often reversible****
Ex. boil, freeze, melt,
cut, grind Solid:
definite shape and volume
tightly packed particles
expand slightly when heated Liquid:
indefinite shape
fixed volume
close contact of particles
not orderly Gas:
indefinite shape
indefinte volume
particles are far apart
easily compressed a measure of the amount of matter that an object contains a measure of the space occupied by a sample of matter

heterogeneous mixture homogeneous mixture Ways to Separate Mixtures
element = simplest form of matter
listed on periodic table
has a unique set of properties
pure substance that can not be broken down
aluminum Distinguishing b/w Pure Substances and Mixtures

pure substance = fixed composition
mixture = composition may vary
Classifying Matter
Copy figure 8 on page 11 on a notecard (or at beginning of your notes for today) anything that has mass and takes up space Chemical Changes:
a new substance is formed
usually not reversible
releases/absorbs energy evidence of a chemical change:
color change
gas forms (bubbles)
precipitate forms compound = 2 or more elements chemically
combined (fixed proportion)

can be broken down into simpler substances
by chemical means

NaCl (salt)
H2O (water)
CO (carbon monoxide atom =
smallest unit of an element that maintains the chemical identity of that element chemical changes are also called chemical reactions
carbon + oxygen -> carbon dioxide

(reactants) (products) all materials are made up of indivisible lumps called atoms (AFM) and (2) atoms have different weight Matter (stuff) is made up of: Atoms Elements in different amounts and arrangements pure substances that can't be broken down
made of only 1 type of atom smallest piece of an element Mixtures composition is not uniform throughout Also called Solution - solutes dissolved in solvent uniform composition
