Its chemical formula, C8H18, reflects the fact that each of the carbons is covalently bonded to one or two of the other carbon atoms and two to three hydrogen atoms. Octane burns really efficiently, so having more octane is good.

Crude oil is predominantly a mixture of straight and branched chain aliphatic hydrocarbons, ranging from gaseous methane to viscous tar-like compounds with up to 80 carbons.

Crude is classified by both physical and chemical characteristics. Crude oil is referred to as either light, medium, or heavy, based on its density. An API gravity lower than 10 means the oil is denser than water and will sink in it. When referring to oil, an API gravity greater than 31.1 degrees is considered light.

Four different types of hydrocarbon molecules appear in crude oil. The relative percentage of each varies from oil to oil, determining the properties of each oil.

Crude oil is a finite resource that is found in the Earth’s crust. It is the remains of organisms that lived and died millions of years ago – mainly plankton which was buried in mud. Crude oil is a complex mixture of hydrocarbons. The carbon atoms in these molecules are joined together in chains and rings.

Answer. Answer: Crude oil is a mixture of comparatively volatile liquid hydrocarbons (compounds composed mainly of hydrogen and carbon), though it also contains some nitrogen, sulfur, and oxygen. Those elements form a large variety of complex molecular structures, some of which cannot be readily identified.

Water and oil is a heterogeneous mixture. It is due to the different viscosity of both the liquids. Due to the high viscosity of the oil it will float over the water surface.

ice is a compound.

A homogeneous mixture appears uniform, regardless of where you sample it. Examples of homogeneous mixtures include air, saline solution, most alloys, and bitumen. Examples of heterogeneous mixtures include sand, oil and water, and chicken noodle soup.

Here are ten examples of homogeneous mixtures:

• Sea water.
• Wine.
• Vinegar.
• Steel.
• Brass.
• Air.
• Natural gas.
• Blood.

It is yes because the drink is a solution of various solids in water. It has the same properties at all points within a sample, as do all (well-mixed) solutions. Since instant coffee is prepared by evaporating such a solution, it is possible that it is a homogeneous mixture too.

Examples of Heterogeneous Mixtures

• Concrete is a heterogeneous mixture of an aggregate: cement, and water.
• Sugar and sand form a heterogeneous mixture.
• Ice cubes in cola form a heterogeneous mixture.
• Salt and pepper form a heterogeneous mixture.
• Chocolate chip cookies are a heterogeneous mixture.

A heterogeneous mixture varies in its composition. Mixtures can be classified on the basis of particle size into three different types: solutions, suspensions, and colloids.

Examples include a mixture of colored candies, a box of toys, salt and sugar, salt and sand, a basket of vegetables, and a box of toys. Mixtures with two phases are always heterogeneous mixtures. Examples include ice in water, salt and oil, noodles in broth, and sand and water.

The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample. Often it is easy to confuse a homogeneous mixture with a pure substance because they are both uniform. The amount of salt in the salt water can vary from one sample to another.

Homogeneous mixtures are mixtures in which the constituents don’t appear separately.

• blood.
• a sugar solution when the sugar is completely dissolved.
• a mixture of alcohol and water.
• a glass of orange juice.
• salty water (where the salt is completely dissolved)
• brewed tea or coffee.
• soapy water.

A pizza is an example of a heterogeneous mixture.

Fruit salad is a heterogeneous mixture because when the fruit is mixed together, it looses it’s composition and mixes together, therefore, forming a salad.

Answer. Fruit salad is a mixture. A mixture contains more than two substances that cannot be combined chemically. Mixtures can be separated by physical means.

Milk, for example, appears to be homogeneous, but when examined under a microscope, it clearly consists of tiny globules of fat and protein dispersed in water. The components of heterogeneous mixtures can usually be separated by simple means.

Because the composition of the solution is uniform throughout, it is a homogeneous mixture. Because its composition is not uniform throughout, orange juice is a heterogeneous mixture.

Ice cream is said to be a homogeneous mixture when it is all the same throughout. That is, nothing has been added to it which is not mixed into it so there are no parts which are different.

Apple juice can be a heterogeneous mixture or a homogenous mixture. The fiber and other nutrients in the apple serve as the solute and the water is the solvent. But, if the apple juice was finely made such that you can only see uniform composition throughout, then the apple juice is a homogenous mixture.

air: mixture; water: pure water is a compound, tap water is a mixture; mercury: pure substance, element; gasoline: homogeneous mixture, liquid-liquid; sugar: pure substance, compound; oxygen; pure substance, element; grain alcohol: pure substance, compound; gold: pure substance, element; salt water: mixture.

Now, since honey is a mixture of various types of sugar compounds and it has identical properties throughout and cannot be separated into its components. So, you can say that honey is a homogeneous mixture.

Coca cola is a homogeneous mixture because the syrup and water are mixed evenly throughout the solution. Also you cant see the basic ingredients of a homogeneous mixture like coca cola, but heterogeneous means that you are able to see the basic ingredients for example a salad, so therefore coca cola is homogeneous.

Whole milk is actually a heterogeneous mixture composed of globules of fat and protein dispersed in water. Milk, for example, appears to be homogeneous, but when examined under a microscope, it clearly consists of tiny globules of fat and protein dispersed in water.

There is no chemical symbol for paper since it is not an element but rather a mixture of several different compounds. The paper we produce today is made from cellulose (which is a single compound) but it is also treated with many chemicals to give it the appropriate texture.
