Respuesta :
I believe the correct answer from the choices listed above is option B. Mixtures are not given chemical formulas because no chemical bonding took place between the components in the mixture such as sugar in water. Sugar in water still remains to be sugar, its properties are the same but only it is dissolved in water.
Answer - B
The definition of mixture is a combination of different things in which the component elements are individually distinct. So chemical bonding takes place and it has no chemical formula.
