What are molecular addition compounds?
Molecular addition compounds are materials formed by weak interactions between a host molecule and one or more guest molecules that are reversibly bound within the host structure. These compounds often exhibit unique physical and chemical properties different from those of the individual components. They are commonly studied in the field of supramolecular chemistry.
What are two ways in which mixtures are different from compound?
- A mixture contain two or more compounds.- A mixture can be separated by physical procedures.
What are the characteristics of a subtances and mixtures?
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.
How are elements compounds and mixtures classified?
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.
Why are all solutions mixtures?
Because solutions contain two or more components.
What are compounds made up of, and how many components do they typically consist of?
Compounds are made up of two or more different elements chemically bonded together. They typically consist of two or more components.
What are two was in which mixtures differ from compounds?
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.
How are elements and compounds the different?
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).
What substances are compounds?
Mixtures contain two or more compounds.
What are two ways a compound differs from a mixture?
- 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

What are two ways in which mixtures are different from compound?
- A mixture contain two or more compounds.- A mixture can be separated by physical procedures.
What is it that contain two or more different types of atom?
All compounds contain more than one element and more than one atom.
What are the characteristics of a subtances and mixtures?
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.
Why is a stone a mixture?
Some stones are compounds, some are mixtures (contain more compounds).
What organic compounds must contain more than one carbon?
Any organic compounds besides methane and methanol contain more than one carbon.
How are compounds and mixtures similar?
A mixture contain two or more compounds.
