If a substance can be separated into its elements, it is a compound. If a substance is not chemically pure, it is either a heterogeneous mixture or a homogeneous mixture. If its composition is uniform throughout, it is a homogeneous mixture.
A compound contains two or more different atoms joined together. A mixture contains two or more different substances that are only physically joined together, not chemically. A mixture can contain both elements and compounds.
Describe the basic properties of each physical state of matter: solid, liquid, and gas. … Classify matter as an element, compound, homogeneous mixture, or heterogeneous mixture with regard to its physical state and composition.
Two principal ways of classifying matter are according to its physical state (as a gas, liquid, or solid) and according to its composition (as an element, compound, or mixture). A sample of matter can be a gas, a liquid, or a solid. These three forms of matter are called the states of matter.
A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds. They contain only one type of molecule.
Elements, mixtures and compounds Common examples include carbon, sulfur, oxygen, iron, copper, aluminium. Elements are represented by symbols. Compounds are substances made from atoms of different elements joined by chemical bonds. They can only be separated by a chemical reaction.
Mixtures can be classified into two main categories: homogeneous and heterogeneous.
- Matter can exist in one of three main states: solid, liquid, or gas.
- Solid matter is composed of tightly packed particles. …
- Liquid matter is made of more loosely packed particles. …
- Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume.
Matter is any thing that is made from atoms and molecules. ( Studios, 1995) . The seven states of matter that I am investigating are Solids, Liquids, Gases, Ionized Plasma, Quark-Gluon Plasma, Bose-Einstein Condensate and Fermionic Condensate. Solid Definition – Chemistry Glossary Definition of Solid.
Matter can exist in one of three main states: solid, liquid, or gas. Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around. Liquid matter is made of more loosely packed particles.
By their chemical composition, pure substances get divided into two types – elements and compounds.
The purpose of classification is to identify objects with common or similar properties. Solids, liquids and gases provide a simple means of classifying the state of matter but they are not the only groupings used by scientists. Some substances are very difficult to ‘classify’.
Some physical characteristics of matter are shape, color, size, and temperature. An important physical property is the phase (or state) of matter. The three fundamental phases of matter are solid, liquid, and gas (Figure 1.2. 1).
As only one type of atoms makes up an element, all the properties of that atom are represented by its atom. In the case of compounds, the same type of molecules makes up the compound. Elements cannot be broken down by chemical reactions. Compounds can be easily separated into simpler substances by chemical reactions.
- A compound always has the same elements in the same proportions. For example, carbon dioxide always has two atoms of oxygen for each atom of carbon, and water always has two atoms of hydrogen for each atom of oxygen.
- A compound always has the same composition throughout.
