is smog homogeneous or heterogeneous?
605880
Smog is a heterogeneous mixture of various particles and pollutants suspended in the air. The dirty particles that make up the smog can be removed from the air and breathed into the lungs, making smog quite a problematic heterogeneous mixture.

Yes, gasoline is a homogenous mixture. Its properties are spread throughout the mixture uniformly without any differences in the mixtures at different places that is why its a homogenous mixture.

Characteristics of mixtures A mixture in which its constituents are not distributed uniformly is called heterogeneous mixture, such as sand in water. One example of a mixture is air. Air is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances.

Heterogeneous grouping is when a diverse group of students is put in the same cooperative learning group. ... Homogeneous grouping is the distribution of students, who function at similar academic, social, and emotional levels, being placed in the same cooperative learning group together.

Gaseous mixtures may contain liquids or even solids, but as a whole, they act as a gas. Mist and fog can be considered heterogeneous mixtures, as tiny droplets of water hang visibly in the air.

Smog differs in the properties with smoke and fog as well. Classical smog is a mixture of sulfur dioxide and coal smoke with fog. Photo chemical smoke is a precipitate in the reaction of the nitrogen oxide and other chemical compounds in Sunlight.

A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture. All solutions would be considered homogeneous.

Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it's also called smog.

Smog is when air pollution hangs over urban areas, and reduces visibility. Smog is formed by chemical reactions that involve sunlight, air, automobile exhaust, and ozone. Smog is an example of a secondary pollutant.

A mixture of soil in water to make "mud" is heterogeneous. Likewise, a mixture of oil and water in salad dressing is heterogeneous. Beach sand is heterogeneous since you can see different colored particles. Homogeneous Mixture – appears uniform and consistent throughout.

In most technical applications homogeneous means that the properties of a system are the uniform throughout the entire system; heterogeneous (also inhomogeneous) means that the properties change within the system. Any system with two phases like ice and water are said to be heterogeneous.

Tap water is homogenous. That is it is a solution with a (very) few things dissolved in it. It is uniform in composition.

A sugar solution is homogeneous since only a colorless liquid is observed. Air with no clouds is homogeneous. For example beach sand is heterogeneous since you can see different colored particles.

There are two main types of mixtures: homogeneous mixtures and heterogeneous mixtures.

A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture. ... A phase is any part of a sample that has a uniform composition and properties. By definition, a pure substance or a homogeneous mixture consists of a single phase. A heterogeneous mixture consists of two or more phases.

Muddy water, on the other hand is a heterogeneous mixture because mud can settle, leaving the mixture with much less mud at the top of the bucket than the bottom. ... Air is homogeneous because.
