What mixture which makes from element or compounds?

it is a chemical change so that is why it becomes a compound from a element


Do different compounds found together but not combined chemically make up an element?

No, different compounds found together but not chemically combined do not make up an element. An element is defined as a pure substance that consists of only one type of atom, characterized by its atomic number. Compounds are formed from two or more elements that are chemically bonded together. Therefore, a mixture of compounds does not change the fundamental nature of the individual elements present.

Can an element be decomposed by chemical change?

Yes, an element can be decomposed into simpler substances through chemical reactions. This typically involves breaking the chemical bonds that hold the element's atoms together, resulting in the formation of new compounds or elements.


Can a material change from one substance to another during a chemical reaction?

"Substance" is too fuzzy a word. Chemical reactions can change materials into other compounds, for example shiny iron into rust (Fe2O3). But it cannot change an element into another element. A nuclear reaction can do that, for example uranium into plutonium.


Is iodine a physical property or a chemical property?

Iodine itself is a chemical element with a physical property, as it is a solid at room temperature and has a distinctive purple color. Its chemical properties involve its reactivity with other elements and compounds in chemical reactions.

Are all reactions that form compounds from elements a redox reaction?

Yes, because an element is in oxidation state ZERO. A reaction is redox only when there is a change in oxidation state of relevant species. So if a compound is formed from elements (as opposed to other compounds) there by definition has to be a change in oxidation state.


If properties of elements change they are mixed together and the mixture if called what?

If the properties of elements change when they are mixed together, the mixture is called a compound. Compounds result from chemical reactions between elements, where the atoms are bonded together in specific ratios. These compounds often possess unique properties distinct from their individual element components.


Why can you write a formula for compounds but not for a mixture?

Because in a mixture, there are no bonds formed between the elements, and therefore the proportions of each element are unknown, for the mixture as a whole. A mixture is not a chemical change.
