-
How many chains are there in the C.O.M, what are they and what is in them?
- There are 2
- #1 includes
- mixtures
- mechanical mixtures+Solutions
- Ordinary mechanical mixtures+suspensions+colloids
- #2
- Pure substances
- Elements+Compounds
-
What is the difference between a homogeneous and heterogeneous mixture?
homogeneous: looks the same throughout ( 1 phase)
heterogeneous: does not look the same throughout (2 or more phases)
-
Define Mixtures
(and is it Heterogeneous or homogeneous?)
- *Made of two or more kinds of molecules (particles)
- Heterogeneous
-
Mechanical mixtures (htg or hmg)
- *Different visual Particles
- *ex. pizza
- heterogenous
-
Solutions (htg or hmg)
- *Different particles
- *Too small to see even with a microscope
- ex. salt water
- Homogeneous
-
Ordinary Mechanical mixtures
- *easy to see different parts
- *ex. bread,eggs
- Heterogeneous
-
Suspensions
- *solid particles that eventually settle out
- *ex. Pond water, raw milk
- Heterogeneous
-
Colloids
- *very small particles that do not settle out but they do scatter
- ex. homo milk
- jello
- Heterogeneous
-
Pure Sunstances
- * made of one kind of atom or molecule
- Homogeneous
-
Elements(atoms)
- *Appear on the periodic table
- ex. hydgen
- Homogeneous
-
Compounds(molecules)
- *Combinations of elements
- ex. H2O
