A mixture is defined as 2 substances that are arbitirarily combined. They are either homogenous or heterogenous.
A substance is defined as being homogenous and has definite, fixed composition that is NOT arbitrary.
On some classwork we did, this following was stated as being true:
wood is a...answer: mixture
sodium chloride is a... answer: mixture
I disagree; wood is a substance because it has a fixed composition by definition. And since sodium chloride is a compound, it is not a mixture either; it is a substance.
the choices for classification on the worksheet was "mixture" or "substance".
I am confused...please help.
thanx
