Chemistry is the study of substances and how they interact with other substances. A substance can be broken into two categories: mixtures or pure substances. In chemistry, a pure substance is an element or compound made up of one type of particle. Pure substances have a fixed structure with ...
In general,any heterogeneous mixtureis not a pure substance. If you can see differences in the composition of a material, it's impure, at least as far as chemistry is concerned. Rocks Oranges Wheat Light bulbs Shoes Sandwiches A cat A computer A house Sand The Gray Area Some substances don...
A pure substance is made up of only one type of particle and has a fixed structure. A mixture, on the other hand, is the physical combination of two or more substances. In this article, we are going to focus on pure substances. In chemistry, the pure substance is a very simple concep...
Understand what liquids are in chemistry, explore the properties of liquids, and discover examples of liquids in science and everyday life. What are Liquids? What is the liquid definition in chemistry? In chemistry, liquids are substances in a slightly mobile state of matter. There are four ...

In most cases, however, these reactions involve stoichiometric...
Today a factor commonly used to distinguish between inorganic and organic substances is the presence of the element carbon. Inorganic chemistry, a vast field of study, is usually defined as the study of any compound that does not contain the element carbon, especially as it occurs in chemically...
If the matter consists of more than one type of particles then it is a mixture. On the other hand, if it consists of a single type of particles then it is a pure substance. We can further classify mixtures into homogeneous and heterogeneous mixtures. Pure substances are also categorised ...
Lewis definition of base in chemistry defines base as a molecule with a high-energy pair of electrons that can donate a pair of nonbonding electrons to the acids that accept it and form an adduct. Properties of Bases Here we have listed some general properties of basic substances or bases....

Science describes an element as a pure substance made of only 1 type of atom that can not be broken down further into other substances. For example, hydrogen (H) and oxygen (O) are elements, but water ({eq}H_{2}O) {/eq} which is made of hydrogen and oxygen is NOT. Why?
