No. Hydrogen is a pure substance and therefore is homogeneous.
homogeneous
Homogeneous.
Heterogenous mixtures are not uniform throughout the liquid. For example flour and water mixture is heterogenous because the flour isn't going to be uniformly located throughout the liquid. Homogenized milk is homogenous, as the concentration of particles throughout the liquid is evenly distributed. Heterogenous mixtues will often "settle", homogenous will not settle over time.
Pond water is not a pure substance.
from the actual sense water is not a pure substance, but if you are classifying it as either heterogenous or hoemogenous, then it is hoemogenous and not heterogenous, now heterogenous are substance that contains different forms eg liquid and solid. But water has one form (liquid)
No. Hydrogen gas is an element, making it a pure substance.
Hydrogen (H) is an element. Hydrogen gas (H2) is a molecule.
Heterogenous
heterogenous mixtures
Heterogeneous. It's a combination of two homogenous substances - hydrogen, and oxygen. What you're describing is hydrogen peroxide, by the way.
It is neither heterogenous nor heterogenous. It is HOMOgenous
Mixtures.
Gasoline is a homogeneous solution.
heterogenous is not a word so there is none.
Sodium chloride is a compound not a mixture.
Distilled water is homogenous not heterogenous.
AnswerIt is heterogeneous as it is made up of many different atoms and molecules... carbon, hydrogen, oxygen as well as pollen and pollutants.Air is a homogenous mixture.
