A compound is a chemical combination of two or more elements in definite proportions. For example, two hydrogen molecules + one oxygen molecule= one water molecule. A solution is a physical combination of two or more chemicals mixed evenly (salt that is dissolved in water). Solutions are also known as homogenous mixtures. A mechanical mixture is a physical combination of two or more chemicals that are not evenly mixed (hot fudge on ice cream). Mechanical mixtures are also known as heterogenous mixtures.
Homogenous: milk, kool-aid, blood, lotion, window cleaner, glue, etc.
Heterogenous: pizza, cereal and milk, rocks in the sand at the beach, banana splits, etc.
Homogeneous mixuters are those in which the components are evenly distributed over the major component/constitute of the mixture.
Eg: blood, milk.
Hetrogeneous mixtures are mixtures are those in which the components are not evenly distributed over the major component/constitute of the mixture.
The very (unevenly distributed) form of heterogeneous mixtures is the reason why most people shake the mixtures before using them.
Eg: Milk of Magnesia, Copper Sulphate
A homogeneous mixture and a heterogeneous mixture are first and foremost both mixtures. That means no chemical bonding has occurred between the substances within the mixtures. They can be separated through physical means if necessary.
The difference between the two mixtures is in how well they are mixed. Heterogeneous mixtures are mixtures that are not well mixed. A person could see the individual pieces that are mixed together. Foods are often great examples of heterogeneous mixtures. For example, a fruit salad is a heterogeneous mixture. So is trail mix and Lucky Charms. Pepper works too, because you can see all of the different pieces that make up pepper.
A homogeneous mixture is a mixture that is really well mixed. It's so well mixed that you can't see the different parts of the mixture. It all looks uniform. The air that you are breathing right now is a homogeneous mixture. It's made up of several different gasses that are so thoroughly mixed together that they appear uniform. Milk is also a homogeneous mixture. It looks uniform throughout. In fact, if you have a gallon of milk in your refrigerator at home, go check the container. It more than likely says "homogenized."
Homogeneity and heterogeneity speak to the distributions of the constituent parts of a sample.
Homogenous samples have consistent distributions of species throughout, so a snapshot taken from any part of the sample would reveal the same makeup as a snapshot taken anywhere else - think of salt that has been dissolved in a pot of water.
Heterogenous samples are differentiated in their composition, and a snapshot at one location may reveal a different makeup than a snapshot taken elsewhere. Think of the planet Earth - at its surface it is composed of solids, but towards its core molten metals and other features can be seen.
Homogeneous mixtures are mixtures in which the constituents don't appear separately.
2. a sugar solution when the sugar is completely dissolved
3. a mixture of alcohol and water
4. a glass of orange juice
5. salty water (where the salt is completely dissolved)
6. brewed tea or coffee
7. soapy water
8. a diluted solution of hydrochloric acid
9. hard alcohol
In heterogeneous mixtures, the constituents appear separately.
1. oil and water
2. a soil sample
3. sandy water
4. a carbonated beverage or beer (the CO2 gas appears separately within the liquid)
5. orange juice with pulp in it
6. water with ice cubes in it
6. chicken noodle soup
Homogenous Mixtures are mixtures which have their components uniformly spread throughout the solution.
1. salt in water
2. sugar in water
3. all true solutions
Heterogenous Mixtures are mixtures which have their components separated throughout the solution.
1. sand in water
2. oil in water
3. all suspensions and colloidal solutions
Homogeneous mixture is a mixture whose material property does not change along any dimension.
If the mixture’s characteristic property changes with respect to dimension it is called the heterogeneous mixture.
Homogenous Mixtures are substances that are uniform in composition on a molecular level. As opposed to Heterogenous Mixtures, which lack the uniformity found in homogenous mixtures.
It's pretty hard to define an example of a homogenous mixture. Pure alcohol and pure water would be good examples.
Blood is actually not really a homogenous mixture because it includes lipids, proteins, steroids, and other biologically important molecules. However, if you centrifuge a sample of blood and separate the cells from the plasma, then the blood plasma is an example of a homogenous mixture.
Here is a simple answer,
Homogenous- You can't pick out a things in a mixture, example, Salt water. You really cant pick out every grain of salt, or soda, you cant pick out all of something in a mixture.
Heterogenous- You can clearly see both two things in a mixture. Like oil in water. You can see the oil floating on top of the water, or something like chicken noodle soup, you can clearly see different things in the mixture.
I hope this helped!
I'm in seventh grade and it's not that hard once you know what homogenous mixtures are.
homogeneous:- hamogeneous mixtures have only one phase.they have the same properties throught a samle although the properties of different samples may be different.hogeneous mixtures are solution
there are three types of homogeneous mixtures
solid homogeneous mixture-alloys
liquid homogeneous mixture-alcoholin water
gaseous homogeneous mixure-air
hetrogeneous mixtures have more than one phase.they do not have the same properties throughout a sample.bits of the phases can be seen either with eye or with a microscope.the phase can be in the same or different physical states
there are three types of hetrogeneous mixture
solid in solid-mixture of sugar and salt
solid in liquid-ice cubes in water
gaseous hetrogeneous mixture-smoke in air
These mixtures are made up of more than one phase or of different parts and can be separated physically. The different components are visibly distinguishable from one another. A chocolate chip cookie, a piece of quartz containing a vein of gold. granite, oil and vinegar, a tossed salad, halo-halo,pizza and a bowl of raisin bran cereal are some examples of hetergeneous mixtures.
Homogeneous mixtures have only one phase, or have a uniform appearance throughout, and any portion of the sample has the same properties and composition. Each region of a sample is identical to all other regions of the sample. Solutions like salt water and rubbing alcohol, are considered homogeneous because they are in one phase. The first is a mixture of salt dissolved in water, while the second is mainly isopropyl alcohol and water.A sample of milk appears to be uniform to the eye, but simple microscopic examination shows it to be heterogeneous. It is a hetergeneous misture containting water,proteins, carbohydrates, fats, and some vitamins and minerals. Mixtures cab be separated physcally. Physical separation methods include filtering, evaporationg, distilling, decanting, crystallizing, sieving, and the use of magnet.
A homogeneous mixture has the same uniform appearance and composition throughout.
A heterogeneous mixture consists of visibly different substances or phases.
- blood (also considered heterogeneous mixture)
- glass bottle
- copy paper
- steel (metal)
- chocolate pudding
- mud water
- water + oil
- orange juice (with pulp)
- water + sand
- mud water
homogenous mixtures are those in which teh composition is uniform like sugar dissolved in water,salt in water etc..where as heterogenous mixture are those in which the components can be easily identified... for examples oil in water,iron fillings and sand ...etc
Homogeneous mixtures have only one phase, & have uniform composition and properties throughout. Each region of a sample is identical to all other regions of the sample. Solutions like salt water and rubbing alcohol, are considered homogeneous (after ample time for the salt to diffuse) Heterogeneous mixtures are made up of more than one phase or of different parts and can be separated physically. The different components are visibly distinguishable from one another. A chocolate chip cookie, a piece of quartz containing a vein of gold, oil and vinegar, a mixed salad, and a bowl of trail mix are some examples of hetergeneous mixtures.
