General Chem

• Matter is anything that has mass and takes up space.
• Toothpaste normally comes as a heterogeneous paste or gels.
• The three states of matter are Solid, Liquid, and Gas.
• Properties are characteristics of a substance that can be observed without changing the composition.
• Intensive properties depend on the type of matter.
• Extensive properties depend on the amount of matter.
• Physical change is a change in the appearance or form of the matter without a change in the kind of matter.
• Element is the simplest type of matter, composed only one kind of atom.
• Compound is a molecule made of atoms from different elements.
• Molecules are atoms that are made up of two or more substances.
• Mixtures are composed of two or more substances and can be seen by the naked eye.
• Solution is the substance that gets dissolved in a mixture.
• Solvent is the one that does the dissolving in a mixture.
• Heterogeneous Mixture is a mixture with two or more phases and does not have a uniform composition.
• Suspensions are mixtures where the suspended particles can be seen.
• Magnetic Separation is normally used to remove magnetic solids.
