Air is generally considered a homogeneous substance because it is a mixture of gases that has a uniform composition throughout. The individual gases, such as nitrogen, oxygen, and carbon dioxide, are evenly distributed, making it difficult to distinguish the different components with the naked eye. However, in certain conditions, such as pollution or humidity, air can exhibit heterogeneous characteristics.
Pure air is homogeneous because all components are completely miscible.
CO2 is a pure substance and so is homogeneous. Hint: if it has a chemical formula then it is a pure substance.
homogeneous
To determine whether Mike is classified as a homogeneous or heterogeneous substance, we need to know the specific context or composition of "Mike." Generally, a homogeneous substance has a uniform composition throughout, like saltwater, while a heterogeneous substance consists of distinct, separate components, like a salad. If Mike is a pure substance with consistent properties, he would be homogeneous; if he contains varied elements or phases, he would be heterogeneous.
heterogeneous and homogeneous is not the same so the substance is homogeneous and the mixture is heterogenous..
Homogeneous substance
pure air is homogeneous but dusty air is heterogeneous
Pure Iron is considered as Homogeneous. Whereas, Iron with rust or other impurities is Heterogeneous.
homogeneous
wood is a heterogeneous substance..
Sugar is a compound, which is a homogeneous substance, but not a mixture.
Pure air is homogeneous because all components are completely miscible.
CO2 is a pure substance and so is homogeneous. Hint: if it has a chemical formula then it is a pure substance.
heterogeneous
homogeneous have same substance in mixture.heterogeneous have two different substance.
homogeneous
Air is a homogeneous mixture.
