What is a substance that is not chemically combined called?​

A mixture is a physical combination of two or more substances where there is no chemical combination or reaction.

Why is a mixture not a chemical combining of substances?​

In a mixture, the substances involved ( can / cannot ) be separated by a simple physical process. In a compound, the elements involved ( can / cannot) be separated by a simple physical process because the elements are (physically combined / chemically bonded ).
What consists of two or more components that are not chemically combined?
A mixture is a material system made up of two or more different substances, which are mixed but not combined chemically. A mixture refers to the physical combination of two or more substances in which the identities of the individual substances are retained.
Are components chemically combined?
Elements can be chemically combined into compounds, therefore, a compound consists of two or more elements combined, in definite proportions, by chemical means. Compounds may be formed by combining atoms of their constituent elements by ionic bonds or by covalent bonds.

What is compound mixture?​

Compound. Mixture. Definition. A compound is the substances that are formed by combining two are more chemical elements. A mixture is a substance created from two or more matter that can be separate with the help of physical methods.

What is heterogeneous and homogeneous?​

A mixture is composed of one or more pure substances in varying composition. There are two types of mixtures: heterogeneous and homogeneous. Heterogeneous mixtures have visually distinguishable components, while homogeneous mixtures appear uniform throughout.
Is heterogeneous or homogeneous?
If you can see more than one phase of matter or different regions in the sample, it is heterogeneous. If the composition of the mixture appears uniform no matter where you sample it, the mixture is homogeneous.
What is homogeneous and heterogeneous in chemistry?
The components of a heterogeneous mixture can easily be seen. A lemonade is a solution of salt (sodium chloride), sugar and lemon juice in water. It is a not a heterogeneous mixture as it has a uniform composition, as well as its components, cannot be distinguished.
What is chemically combined?
The combination of elements to give compounds.
What are compound molecules?
Molecules of compounds have atoms of two or more different elements. For example, water (H2O) has three atoms, two hydrogen (H) atoms and one oxygen (O) atom. Methane (CH4), a common greenhouse gas, has five atoms, one of carbon (C) and four of hydrogen (H, see Fig. 2.9).

What is a compound or a molecule?​

Molecules are formed by two or more atoms that are bonded by chemical bondings. Compounds are constructed by two or more elements where the elements are mixed in fixed ratios. Not all molecules can be called compounds.

What is called compound?​

1) In chemistry, a compound is a substance that results from a combination of two or more different chemical element s, in such a way that the atom s of the different elements are held together by chemical bonds that are difficult to break.
What is the difference between H * * * * * * * * * * and heterogeneous mixture?
1. A homogenous mixture is that mixture in which the components mix with each other and its composition is uniform throughout the solution. A heterogenous mixture is that mixture in which the composition is not uniform throughout and different components are observed.
