25
-does not depend on the amount Something of substance present Determine by the chemical composition of the particles and their structure ( arrangement ) ( intensive - internal )
Intensive Property
26
One does depends on the amount of substance present Depend only on the amount of particles, not on their composition or internal arrangements ( external - extensive)
Extensive Property
27
Structure of diamond

30
taking of electrons
Ionic
31
sharing of electrons
covalent
32
Only quality that is observed through chemical reactions
Chemical Property
33
A trait of matter that can only be observed if a substance has the property In the process of testing the chemical Property, the substance change composition it it has that property
Chemical Property
34
-rusting ( iron) tarnishing ( silver, copper, brass, etc.)
Reactivity with oxygen Chemical Property
35
tendency of a substance to chemicaly react w/ water
Reactivity with water Chemical Property
36
tendency of a substance to chemically reacts with acid
Reactivity with acids or bases Chemical property
37
tendency of matter to burn
Combustibility/Flammability
38
- tendency of matter to burn
Combustibility/Flammability
39
What something is made of is always a Chemical property
Chemical Formula ( chemical composition)
40
Chemical formula of Rust Water Diamond
Rust - Fe2O3 Water - H20 Diamond - C
41
All chemicals properties are intensive, none are extensive Why?
Because chemical properties never depend on how much a substance is present, but only on what kind of particles make up the substance
