Is octane miscible in methane?
Octane is immiscible in methane because they have different intermolecular forces and polarities. Octane is a nonpolar molecule, while methane is also nonpolar. They will not mix together to form a homogeneous solution.
What is the name of the unbranched alkane with eight carbon atoms?
The fourth of the methane series. Methane, ethane, propane, butane, pentane, hexane, heptane, octane, ... Fourth is butane, like in a bic lighter.
Since water is a much smaller molecule than octane C8H18 one would expect it to flow more quickly However studies show that water is almost four times as viscous as octane How can this be explain?
Octane molecules have almost no interaction with each other but water molecules link up together via a process called hydrogen bonding. This increases the viscosity, boiling and melting points for water.
When compared to high viscosity liquid a liquid with a low viscosity does what?
A liquid with low viscosity flows more easily and rapidly compared to a high viscosity liquid. This is because low viscosity liquids have weaker internal friction between their particles, allowing them to move more freely.
What is the term for the thickness of a liquid?
The term for the thickness of a liquid is viscosity. This property determines how easily the liquid flows and is influenced by factors such as temperature and composition. A high viscosity liquid is more resistant to flowing, while a low viscosity liquid flows more easily.

How can you obtain methane from octane?
Methane can be obtained from octane through a process called cracking, which involves breaking down larger hydrocarbons into smaller ones. This can be achieved through thermal or catalytic cracking, where octane is subjected to high temperatures and/or the presence of catalysts to facilitate the breakdown of its molecular structure. The resulting smaller hydrocarbons can include methane, along with other alkanes. Additionally, complete combustion of octane in a controlled environment can yield methane as a byproduct, although this is not the primary method for methane production.

Why does octane have a higher boiling point then water?
Octane is a straight chain molecule with a large surface area and stacks easily with other octane molecules. This increases the strength of the London dispersion forces that keep the octane molecules attracted to each other. The London dispersion forces on octane are greater than for smaller straight chain molecules because octane is both heavier and has more electrons that make it more polarizable.
What is octane?
Octane is an alkane hydrocarbon with the chemical formula C8H18.
Pentane Methane Propane Octane Which of these chemical formulas represents the formula for C3H8?
propane
What do methane octane butane have in common?
Methane, octane, and butane are all hydrocarbons, meaning they consist of carbon and hydrogen atoms. They are also all considered alkanes, which are saturated hydrocarbons with single bonds between the carbon atoms. However, they differ in the number of carbon atoms they contain, with methane having one, butane having four, and octane having eight.

Octane and methane are both carbon and hydrogen atoms why are they different?
Octane and methane are both saturated hydrocarbons and follow the formula CnH2n+2. The only thing that's different is the number of carbons (and hence hydrogens) in the backbone. Octane has 8 carbons and has formula C8H18. Methane has 1 carbon and has formula C1H4.
How does the number of bonds affect the dispersion forces in samples of methane octane?
The number of bonds in a molecule influences its size and shape, which in turn affects dispersion forces. Methane (CH₄) has a simple tetrahedral structure with fewer electrons, resulting in weaker dispersion forces compared to octane (C₈H₁₈), which has a larger, more complex structure with more electrons. As a result, octane experiences stronger dispersion forces due to its greater surface area and increased polarizability, leading to higher boiling and melting points compared to methane. Thus, the number of bonds and the associated molecular size play a critical role in the strength of dispersion forces.
Are organic liquid vapors flammable?
Methane and octane, both alkanes, are examples of gases that are used as fuel and are highly flammable.
What are compounds that contain carbon and hydrogen atoms?
Hydrocarbons which include gasoline, methane, ethane, propane, butane, octane etc
