Urban air contamination is a serious problem in many of the planet's big cities. Intense and unremitting traffic, together with uncontrolled factory emissions, convert city air worldwide into authentic clouds of smog. ... This figures means that in 2012 one of every eight deaths worldwide was linked to air contamination.

Normal urine It is homogeneous because it has the same composition throughout. d. Smog-filled air It is heterogeneous because it does not have the same composition throughout (concentration of smog, oxygen, other gases depends on the altitude).

A mixture in which its constituents are distributed uniformly is called homogeneous mixture, such as salt in water. A mixture in which its constituents are not distributed uniformly is called heterogeneous mixture, such as sand in water.

Being heterogeneous they have two states of matter mixed together. For example milk is a mixture of water and fats. ... Suspensions are heterogeneous mixtures from which some of the particles settle with time. Muddy water is a classic suspension, with relatively large solid particles suspended in water.

When two or more substances are mixed together, the result is called a mixture. ... A heterogeneous mixture is a nonuniform mixture in which the components separate and the composition varies. Unlike the homogeneous mixture, heterogeneous mixtures can be separated through physical processes.

On the other hand, a heterogeneous mixture is a type of mixture in which the makeup is not the same throughout. Heterogeneous mixtures are not mixed evenly, so they do not appear uniform. Examples of heterogeneous mixtures include pizza and peanut butter and jelly sandwiches.

A homogeneous mixture is uniform, which means that any given sample of the mixture will have the same composition. Air, sea water, and carbonation dissolved in soda are all examples of homogeneous mixtures, or solutions. ... The substance that gets dissolved is the solute.

(a) Soil is heterogeneous, or a mechanical mixture, because you can see more than one part. (b) Perfume is a solution, or homogeneous. You can see only one part, but perfume is a mixture of ingredients.

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.

In heterogeneous mixtures, two or more ingredients (or phases, regions with uniform composition and properties) intermingle, but remain physically separate. Often it is possible to separate the original ingredients by physical means, such as filtering.

Homogeneous mixtures have uniform properties throughout 2. Heterogeneous mixtures contain more than one part, and each part has its own properties 3. Components of a homogeneous mixture are visibly distinct.
