Respuesta :
That sample of smoke is best described as a mixture and heterogeneous mixture.
It is a mixture because it is formed by different elements, compounds and substance, and so its composition is not constant: one sample of smoke may have different composition that other sample of smoke.
It is heterogeneous because the components may be differentiated with physical methods.

Answer:
Mixture and heterogeneous mixture.
Explanation:
As it is given that the smoke sample contains dust particles and several different gases, which have different combinations of molecules, and the dust particles are also suspended in the gases. The given information states that there are different types of substances which have not combined chemically and they are not present in any fixed ratio , and thus are considered as mixtures.
Also the dust particles can be easily distinguished from the gases and thus there is a distinct boundary between them, which means it is a heterogeneous mixture.
Further Explanation:
Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present. Example: Air
Heterogeneous mixtures : It is a mixture that has non-uniform composition throughout the solution and the particle size or shapes are also different. There is a physical boundary between the dispersed phase and dispersion medium. Example: oil in water
Homogeneous mixtures : It is a mixture that has uniform composition throughout the solution and the particle size or shapes are not different. There is no physical boundary between the dispersed phase and dispersion medium. Example: sugar in water
Solution: It is a homogeneous mixture of two or more components. The component/components present in lesser quantities are termed as solutes and the component present in higher quantity is termed as solvent. Example: sugar dissolved in water
Pure substances: It may be defined a substance that contains one kind of atoms or molecules and has constant composition throughout the sample. Example: Nitrogen [tex](N_2)[/tex]
Element is a pure substance which is composed of atoms of similar elements.It can not be decomposed into simpler constituents using chemical reactions. Example: Copper [tex](Cu)[/tex]
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: water [tex](H_2O)[/tex]
