In class today we graded our quizzes and took some notes on matter, molecules, compounds, etc. After that we had some class time to do out homework!
Notes:
-Matter: has mass and takes up space (volume)
-Mass is the amount of matter
-Atom is smallest unit of matter
-116 different types of atoms = elements
-Atoms bonded together = molecules
Molecules vs. Compounds
-Molecules: any 2 or more atoms bonded together
-Compounds: 2 or more DIFFERENT types of atom bonded together
-Combinations of different atoms and or molecules = mixture
-If only one type of atoms or molecule is present = pure substance
Mixture vs. Pure Substance
-Mixture: combination of 2 or more different atoms or molecules
-Pure Substance: only 1 type of atom or molecule
States of Matter
-Solid: atoms/molecules close together moving slowly
-Liquid: atoms/molecules medium distance moving faster
-Gas: atoms/molecules far apart moving faster
-Aqueous (aq): molecules dissolved in solution
Thats All!
next scriber is Kat!
