air is a mixture of elements.so is water.
Air-it has hydrogen,oxygen,nitrogen,carbon di oxide,water vapour etc but in different proportions so it is a mixture of elements.
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.
Two or more substances mixed together but not chemically combined form a mixture.
Lime is a compound.
It is a element
No, it is a compound, not a mixture. Its formula is MgO, and it contains Magnesium and Oxygen (two fairly common elements).
Distillation
An alloy is a mixture of Metals. A mixture is a combination of elements in an unfixed ratio. A compound is a mixture of elements in a fixed ratio.
A mixture is a collection of elements.
The most common kind is a mixture of metallic elements, called an "alloy".
Milk is an emulsion and a mixture.
They are elements not compound mixture
Smoke is a heterogeneous mixture.
No, unless all the elements involved in the mixture are present in fixed atomic proportions to one another that are ratios of integers, thereby showing that the elements are chemically bonded.
Ketchup is not on the periodic table of elements therefore it is not an element. Ketchup does not have a single chemical name like H20 (water) or H2SO4 (Sulphuric Acid), therefore is not a compound. Ketchup consists mainly of a mixture of vinegar and tomatoes, which aren't elements or compounds themselves, therefore ketchup is a mixture of a lot of molecules.
a mixture of elements can be a compound or simply a mixture. a compound is two or more elements of the periodic table joined together chemically. a mixture is where they are connected but not connected chemically. ask your chemistry teacher or something.
No a mixture is by definition not a pure substance.
mixture as the elements are not chemically bonded :)
