Notes on Properties Webpage
1) A property is the basic characteristics of a substance so that you can define them. Some type of observation.
2) Extensive property
3) intensive (chemical properties)
4) The base units are not changing
5) When the base units rearrange-new arrangements to create base particles
Notes on Physical and Chemical change
6) The main difference is the fact that the base units don’t change in physical properties and chemical properties can change or rearrange.
7) True
8a) Released from system to the surrounding
8b) Requires energy to be put into the system from the surrounding
9a) Law of Conservation of Mass (matter cannot be created or destroyed) and Law of Conservation of Energy (energy cannot be created or destroyed)
Phases of Matter - Physical Change
10) Particles are not changing throughout all of the stages of matter
11a) Solid - Vibrate in 3D space
11ai) Occupy its own shape
11aii) Very compact
11aiii) low amount of energy (not enough to "push" IMF to move in 3D space
11b) Liquid: they have enough energy to "push" IMF to move into 3D space.
11bi) Occupies shape of container
11bii) Close together but not compact
11biii)Greater amount of energy (enough to "push" against IMF to be able to move in 3D but not enough to overcome IMF "completely")
Note: Condensed phase is name people give to either solid or liquid phase
11c) Gas def: particles have enough energy to "overcome" IMF and can go anywhere
11ci) Can take any shape container
11cii) Occupies all volumes
11ciii) Greatest amount of energy
11d) A "sea" of nucleus of atoms and free flowing electrons (and a lot of energy)
Notes from Observation of a Chemical Reaction
12a)Permanent color change
12b) Gas is generated (what odor is)
12c) Energy change
12d) Precipitate is formed (solid from when two or more solutions combine)
13) Yes - will explain in class
