  • In this video we will learn about how all matter is classified. We will learn about puresubstances, heterogeneous mixtures and homogeneous mxtures.

    why is it that I learn more from youtube than from sitting in my classes listening to lectures?? thanks for the video!!!

    Air is a mixture of oxygen gas, nitrogen gas, water vapor, maybe some methane gas if you had some taco bell last night, and several other gases. These gases are not chemically bonded together but simply mixed together. If you wanted to separate the gases from one another you could do so using a physical process. Every breath of air you take into your lungs is about the same. This is because the air we breathe is a homogeneous mixture. It is all mixed nice and evenly throughout. Hope this helps

    What is it called when you mix two chemicals and it takes the form of the one that is most pure? I may be saying it wrong, it's something I vaguely remember learning in grade school years ago.

    Why are the 14k gold and sterling silver homogenous mixtures? They are alloys right? Alloys are considered as solid sols which is an example of a colloid. And colloids are under heterogeneous mixtures. So why is it a homogenous mixture? I'm a bit confused.

      Because of chemical bonds, compounds still require a chemical process to separate, while mixtures only require a physical process.

      Beer is heterogeneous because of bubbles that separate from the liquid, not unless you remove it therefore it is homogeneous.
