Why are elements and compounds pure substances while a homogeneous mixture is not?
Well, elements and compounds are pure substances. This is because the atoms in an elements are of one type only. Thus making it pure. But in a compound, the ratio of the masses of the combining elements or compounds are fixed. For example, the ratio for hydrogen and oxygen to combine together to form water is 1:8. Therefore the compound is also a pure substance. But homogenous mixtures are not pure substances as the components can be mixed in any ratio. We can make brine solution by mixing any amount of salt and water. There is no fixed ratio. So homogenous mixtures are not pure.
What else can I help you with?
What a solution in chemistry?
A homogeneous mixture. A physical combination of two or more pure substances, such as elements or compounds.
Is sugar pure water a pure substance or a mixture?
cake
How is a compound similar to a homogeneous mixture and how is it different?
Both compounds and homogeneous mixtures are made of more than one element and are homogeneous. However, compounds must be made from elements in an exact ratio and involve chemical bonds between the elements in them.
Substances are either elements or mixture?
Substances are Either an element or a mixture
Is spices a compound a element a homogeneous mixture?
a plant is neither a compound or a mixture. anything with a cellular structure has little relevance to chemistry. DNA in a plant contains differant chemicals that are all compounds and single elementsplant is a mixture
Is an element and a compound heterogeneous?
NO!!! Elements and compoounds exists as separate entities. Heterogeneous means a mixture of substances that are in different physical states. Compare to Homogeneous which means a mixture of substances that are in the SAME physical state. However, The element bromine(Br) is liquid at STP. The compound water(H2O) is also a liquid at STP. When mixed together to form bromin water, it is an homogeneous mixture.
Is motor oil homogeneous mixture or a compound?
Motor oil is a homogeneous mixture composed of various compounds such as base oils and additives. It is not a single compound but a combination of different substances that are uniformly distributed throughout the oil.
Can Homogeneous mixture be decomposed into other substances by chemical processes?
No, a homogeneous mixture cannot be decomposed into other substances by chemical processes because it consists of uniform compositions of elements or compounds that retain their properties. In a homogeneous mixture, the substances are evenly distributed and can be separated physically, but their chemical composition remains unchanged.
Does Mixture may consist of elements and compounds?
Yes, a mixture may consist of elements and compounds. A mixture is formed when two or more substances are physically combined without forming a new substance, so it can contain elements and compounds in various proportions.
Are elements and elements a homogeneous mixture?
No, elements are pure substances. However, if you mix two elements together, it depends on how well you mix them. Mixtures of two elements can be completely homogeneous, or extremely heterogeneous.
How is a compound similar to a homogeneous mixture How is it different?
Both compounds and homogeneous mixtures are made of more than one element and are homogeneous. However, compounds must be made from elements in an exact ratio and involve chemical bonds between the elements in them.
What is an incorrect description Question options A homogeneous mixture A heterogeneous compound A solid element A mixture of solids A solution of gases?
A solution of gases is not correct. it should be a mixture of gases
