This is by definition.
If you react a sample of some element with some other element or compound the result will usually be a mixture of some of the unreacted sample and a new compound or compounds that are the results of the reaction. In other words, the resulting substance will no longer be homogeneous.
What else can I help you with?
Is pure substance uniform composition?
Yes, a pure substance has a uniform and definite composition. It is made up of only one type of element or compound, with consistent proportions of its constituent particles. This uniformity distinguishes pure substances from mixtures, which can contain multiple substances in varying proportions.
Form of matter that have definite shape and unchanging chemical composition?
This is a solid.
Is helium and example of heterogeneous?
No, helium is not an example of a heterogeneous substance. Helium is a pure element, which means it is uniform in composition throughout and does not contain different types of molecules or substances mixed together.
What is a uniform mixtures?
A uniform mixture is : A sample of matter that has the same composition and properties throughout.
How is homogenoues different from heterogenous?
Homogeneous mixtures have uniform composition throughout, with the same properties in all parts. Heterogeneous mixtures have non-uniform composition, with distinct phases or regions that can be visually identified.
Matter has a uniform and definite composition called what?
Substance, classified as an element and compound. For an element, it cannot be separated into another simplier substance; for a compound, it can be dicomposed into elements using chemical processes.
Is pure substance uniform composition?
Yes, a pure substance has a uniform and definite composition. It is made up of only one type of element or compound, with consistent proportions of its constituent particles. This uniformity distinguishes pure substances from mixtures, which can contain multiple substances in varying proportions.
Matter that has a uniorm a unchanging composition is know as an?
It is a Substance
What is uniform composition?
a pure substance. either a compound or an element. Also, a solution, which is a homogeneous mixture, not a pure substance.
What is difference between a solution and a substance?
A substance is matter that is uniform in composition. A substance can be an element or compound. A solution is another name for a homogeneous mixture. It is also uniform in composition, but a solution is made by physically combining two or more substances.
Form of matter that have definite shape and unchanging chemical composition?
This is a solid.
What is a mixture with a uniform composition?
A mixture whose composition is uniform throughout is called Homogeneous Mixture.
Does a heterogeneous mixture is one that has a completely uniform composition?
no, heterogeneous mixtures are not uniform, homogeneous mixtures have a fully uniform composition.
What is a substance that has a uniform chemical composition throughout.?
The substances which are all having uniform chemical composition through out are all known as homogeneous substances.
What is the term for matter having indefinite composition and variable properties?
The term for matter having indefinite composition and variable properties is a mixture. Mixtures can be homogeneous (uniform composition) or heterogeneous (non-uniform composition).
Is helium and example of heterogeneous?
No, helium is not an example of a heterogeneous substance. Helium is a pure element, which means it is uniform in composition throughout and does not contain different types of molecules or substances mixed together.
A mixture that has a uniform composition throughout?
Suspension.
