     • A mixture is formed when two or more elements or compounds are present without being chemically bonded together. The substances which have been mixed are not present in specific amounts or ratios like they are in a compound, e.g. two hydrogen atoms for each oxygen atom in water.

   A compound is a substance that contains two or more elements chemically combined in a fixed proportion. The elements carbon and hydrogen combine to form many different compounds. One of the simplest is called methane, in which there are always four times as many hydrogen atoms as carbon atoms.

   When we mix two different pure substances together, like this, it’s a mixture. This is now a mixture of the elements iron and sulfur. The different elements are not joined together.

   Compound: two or more different atoms bonded together. Mixture: two or more different atoms together but not joined. Molecule: two particles (same or different) bonded together. Element: only 1 type of atom; this definition is applied to things both bonded and not to itself.

   A compound consists of two or more different elements chemically combined together. Some compounds are made up of molecules, where some fixed number of atoms are bonded to each other. Others consist of giant structures containing huge, but variable, numbers.

   The law of constant composition can be used to distinguish between compounds and mixtures of elements: Compounds have a constant composition; mixtures do not. Water is always 88.8% O and 11.2% H by weight regardless of its source. Brass is an example of a mixture of two elements: copper and zinc.

9. People also ask

   What is an example of a mixture of two elements?

   • Brass is an example of a mixture of two elements: copper and zinc. It can contain as little as 10%, or as much as 45%, zinc. Another difference between compounds and mixtures of elements is the ease with which the elements can be separated. Mixtures, such as the atmosphere, contain two or more substances that are relatively easy to separate.

   What if a molecule is not a mixture?

   • If one atom, then not molecule and not mixture and not compound. If two atoms and same element, then molecule and not compound and not mixture. If two atoms and not same element, then compound and molecule and not mixture. If two different molecules and evenly mixed, then homogeneous mixture.

   What is a mixture of two different substances called?

   • Combinations of different substances are called mixtures. Homogeneous mixtures are mixtures of two or more compounds (or elements) that are not visually distinguishable from each other. Heterogeneous mixtures are mixtures of two or more compounds (or elements) that are visually distinguishable from one another.

   What is the difference between a mixture and an element?

   • Element: one single atom. A mixture contains two or more substances (elements, lattices, molecules, compounds), that are not chemically bonded together. So basically a mixture is like you said a bath tub with elements, compounds, lattices, and/or molecules in it but they are not bonded together chemically.

   • If two atoms and same element, then molecule and not compound and not mixture. If two atoms and not same element, then compound and molecule and not mixture.

    If we take two or more pure substances and mix them together, we refer to this as a mixture. Mixtures can always be separated again into component pure substances, because bonding among the atoms of the constituent substances does not occur in a mixture.
