Are soaps amphipathic molecules?
Yes, soaps are amphipathic molecules. They have both a hydrophilic (water-attracting) and a hydrophobic (water-repelling) end. This allows them to interact with both water and oil, making them effective in removing grease and dirt during cleaning.
What material are stored in metal with cover?
cooking oil and gasoline
What are the materials stored in metals with covers?
cooking oil and gasoline
What are different types of oil?
Well for one thing there are 2 types of oil 1 gasoline oil and 2 cooking oil
Why is soap amphipathic?
Soap is amphipathic because it contains molecules with both hydrophilic (water-attracting) and hydrophobic (water-repelling) regions. The hydrophilic region allows soap to dissolve in water, while the hydrophobic region enables it to bind to and lift away dirt and oil, making it an effective cleaning agent.
Is cooking oil a heterogeneous or a homogeneous mixture?
Cooking oil is a homogeneous mixture because it is a uniform combination of different types of oil molecules that are evenly distributed throughout the mixture.
Is automobile oil gasoline?
No, oil is oil and gasoline is gasoline, although gasoline is refined from crude oil.
Is table salt soluble in cooking oil?
Table salt (sodium chloride) is not soluble in cooking oil because salt is hydrophilic (water-loving) while oil is hydrophobic (water-repelling). The polar nature of salt molecules does not allow them to dissolve in nonpolar cooking oil.
Why does gasoline have a lower boiling point than fuel oil?
The size of molecules determine how well the molecules hold together/attract each other. Gasoline has a molecular mass of around 114 units whereas fuel oil is a bigger molecule by about a factor of 3 or more. This means boiling point is higher for fuel oil because you have to break apart the molecules to get them to boil. (Boiling is vaporizing the substance.) This same chemical property means that gasoline is less viscous more volatile than fuel oil.
Can you mix oil and gas to run in diesel?
No - they are not designed to run on gasoline. You need diesel fuel or some can be run on vegetable oil or cooking oil but not gas it will wreck your engine. It detinates too hot.
How do they make gasoline?
Gasoline is primarily produced from crude oil.Crude oil is a mixture of hydrocarbons with different molecular weights, formulae, boiling points, contaminants and other physical constants. Gasoline is a hydrocarbon mixture with a much more limited range of these components which is formulated to burn in internal combustion engines.The Process:Incoming crude is cleaned up by removing water and solids.Initially the gasoline sized molecules re removed from the crude oil by distillation. This is a small portion of the crude.The molecules too small to be gasoline are recovered and reformed to make bigger molecules. This reformate is redistilled to recover more gasoline sized molecules. Lighter molecules are added to the crude light ends going to the reformer for another trip through.Heavy molecules from the crude and heavy molecules from the reformer are set to a "Cracker" to be broken up into smaller molecules. This cracked oil is distilled. Gasoline sized molecules are recovered, light ends are reformed and heavy ends are re-cracked.The collected gasolines is purified to remove sulphur and other contaminants, adjusted with other thypes of hydrocarbon molecules to produce a clean burning fuel. Additive packages are mixed in (anti-knock compounds, detergents, antioxidants etc.)
Do cars use gasoline?
Some do. Some don't. Some cars run on diesel, some run on propane, some run on cooking oil
