No, that ain't necessarily so
Yes
A compound contain two or more different elements.
- A mixture contain two or more compounds.- A mixture can be separated by physical procedures.
The components of a mixture are not chemically combined and do not have a definite composition. A pure substance is either an element or a compound (in which case it is composed of elements that are chemically combined) and has a definite composition.
Elements and compounds are pure substances. Elements are composed of only one kind of atom and compounds are composed of two or more elements that are chemically combined. Mixtures are not pure substances, as they are composed of two or more components that are not chemically combined.
No. Chemical compounds contain two or more different elements. H2O is a compound that does not contain a metal.There are many other examples, all the organic compounds for instance.
A compound comprises the same proportion of its components, a mixture can be made up of varying amounts.A compound may have physical and chemical properties which are quite different to those of any of its components. A mixture retains many of the physical and chemical properties of its main ingredient.
A compound contain two or more different elements.
Elements contain only one type of atom (atoms with the same number of protons). Compounds contain more than one element, and thus contain atoms with different numbers of protons. Compounds can be converted into elements, but elements are not reducible to anything simpler (besides subatomic particles).
- a compound contain chemical bonds between atoms - a mixture can be decomposed in components by simple physical methods - a mixture contain two or more compounds
Mixtures contain two or more compounds.
All compounds contain more than one element and more than one atom.
- A mixture contain two or more compounds.- A mixture can be separated by physical procedures.
The components of a mixture are not chemically combined and do not have a definite composition. A pure substance is either an element or a compound (in which case it is composed of elements that are chemically combined) and has a definite composition.
Some stones are compounds, some are mixtures (contain more compounds).
Elements and compounds are pure substances. Elements are composed of only one kind of atom and compounds are composed of two or more elements that are chemically combined. Mixtures are not pure substances, as they are composed of two or more components that are not chemically combined.
Any organic compounds besides methane and methanol contain more than one carbon.
A mixture contain two or more compounds.
