Mixtures
Air is a mixture of mostly nitrogen (N), oxygen(O) carbon dioxide (CO2). Next >
Other times it is more difficult to see what is in a mixture, like with the air we
breathe.

Homogeneous Mixture
Heterogeneous Mixture
Dissolving salt in water:It’s hard to tell whether a new substance forms when
salt dissolves in water.What type of mixture is this? Why?
Everything in the mixture looks the same.
Inquiry: What are mixtures?

Inquiry: How can different mixtures be separated?
Journal Entry
1) Draw a CO molecule Vs.2) Draw C and O atoms
C O C O
The 2 different elements are connected, creating a compound.
The chemical formula CO tells us that the atoms are connected.
The 2 different elements are NOT connected.
They are just separate atoms.
