Most things that you come across in life are not pure - they are combinations of different things. When the individual components of such combinations retain their properties, we have a mixture. Because mixtures are physical combinations of elements and compounds, they can be separated through phys...

Examples of Mixtures Crude oil: A mixture of organic compounds (mainly hydrocarbons) Seawater: A mixture of various salt and water. Air: a mixture of various gases like oxygen, carbon dioxide, nitrogen, argon, neon, etc. Ink: A mixture of coloured dyes. Gunpowder: A mixture of sulfur, pot...
Atomic Number Density of Mixtures and Compounds For a chemical compound (mixture) Z or for an isotopic mixture, which is composed of elements or isotopes X and Y, the number (atom) density of the compound is calculated from: Example – Atomic number densities of ...
Mixtures Definition - A mixture contains two or more elements or compounds that are not chemically combined together. To learn about Homogeneous and Heterogeneous mixtures click here.
While pure substances are usually made of one kind of particle and have a constant and fixed structure, homogeneous mixtures are made of two or more compounds of varying ratios. For example, the amount of sweetener in the soft drink can vary from one sample to another. ...
Examples of Compounds: 1. Water - Formula: H2O = Hydrogen2+ Oxygen Two atoms of the element Hydrogen combine with one atom of Oxygen through a covalent bond to form water. Hydrogen has a slightly positive charge and oxygen has a negative charge, and therefore it forms a polar molecule. Wa...
Reagent Examples Reagents may be compounds or mixtures. In organic chemistry, most are small organic molecules or inorganic compounds. Examples of reagents include Grignard reagent, Tollens' reagent, Fehling's reagent, Collins reagent, and Fenton's reagent. However, a substance may be used as a ...
