Chem — Introduction to Matter and its Classification + 6 more topics

When we go beyond basic classifications like combination, decomposition, single displacement, double displacement, and combustion, we start looking at the fundamental changes happening. This often involves tracking electrons, energy, and specific bond formations/breakages.

In chemistry, a mixture is formed when two or more substances are combined but not chemically bonded together. This means each substance retains its original chemical properties. You can often separate the components of a mixture using physical means (like filtering or evaporation), unlike compounds where separation requires chemical reactions.

There are two main types of mixtures:

Matter is anything that has mass and occupies space. Mass is a measure of how much "stuff" is in an object, while volume is the amount of space that object takes up. All matter can be broken down into two main categories: pure substances and mixtures.

When we talk about "pure substances" in chemistry, we're referring to materials that aren't mixed with anything else. Think of pure gold or pure water; they have a consistent makeup no matter where you find them.
