Diffusion of nonpolar molecules would not be affected by?
Diffusion of nonpolar molecules would not be affected by factors such as temperature, concentration gradient, or the presence of other nonpolar molecules. Nonpolar molecules are able to diffuse freely through cell membranes and other barriers due to their lack of charge, making them less influenced by these factors compared to polar molecules.
Why do small nonpolar molecules cross a membrane?
Small nonpolar molecules can cross a membrane easily because they are able to pass through the lipid bilayer of the membrane due to their size and lack of charge, allowing them to move freely across the membrane.
What is best descrinbed as a biologic solvent?
A biologic solvent is a substance that can dissolve other biological molecules, such as proteins or lipids, without causing damage to them. Water is the most common biologic solvent in living organisms, as it is able to dissolve a wide variety of molecules due to its polar nature and ability to form hydrogen bonds.
What determines whether a compound will dissolve in water?
Water is known as a very polar solvent. That is, the molecules have localized area of concentrated electrical charge. The oxygen atoms are regions of (-) charge and the hydrogen atoms are areas of (+) charge. These areas of localized charge want to interact with neighboring areas of opposite charge. So, oxygen atoms tend to form loose bonds with hydrogen atoms on other nearby water molecules. This lowers the energy of the entire system and therefore promotes stability. For this reason any compound that is able to mimic the tendency of a water molecule to interact with another water molecule will ensure that the compound will indeed enter into association with water (that is, dissolve). The occurrence of groups containing local charge on the solute molecule ensure its ability to dissolve in water. Specifically, polar groups such as OH, NH, CO are associated with the ability to dissolve in water. Certainly the occurrence of net charge (+/-) on a molecule that contains an ionizable group (COOH, NH2, PO4, etc) is a good indicator of water solubility.
What is the definition of the term autotroph?
An autotroph is an organism that can produce its own food using inorganic compounds as a source of energy, typically through photosynthesis or chemosynthesis. Autotrophs are able to sustain themselves without consuming other organisms.
What property enables chloroform to dissolve lipids?
Chloroform is a nonpolar solvent, which means it can dissolve other nonpolar substances like lipids. Lipids are also nonpolar molecules, so they are able to dissolve in chloroform due to their similar polarity. This allows chloroform to effectively solubilize lipids.
Substance A is a Molecular compound that dissolves in gasoline but not water. The molecules of A are very likely....what?
Nonpolar. Molecules that dissolve in nonpolar solvents like gasoline tend to be nonpolar themselves, as nonpolar substances are attracted to each other through London dispersion forces. Water, being a polar solvent, is not able to dissolve nonpolar molecules as effectively.
What would dissolve best in oil?
Substances that are nonpolar or nonpolar complexes, such as lipids, certain flavors, and some drugs, dissolve best in oil. Examples include essential oils, vitamin A, and vitamin E. Oil is not able to dissolve polar substances like water-soluble vitamins or salts.
Why cant water dissolve compounds such as oil?
Water is a polar molecule, while oil is a nonpolar molecule. Polar molecules like water are only able to dissolve other polar or ionic substances, not nonpolar substances like oil. This is due to the differences in their electrostatic interactions, preventing water from effectively breaking down and dissolving oil molecules.
What substances that do not dissolve easily in water?
you know water is a polar substance and can solve only polar substances and ionic substance it is not able to solve fat , oil or other organic (usually) substances (oil). by ionic substance I meant substances such as salt
Why are some substances not able to be dissolved in water?
Some substances are not able to dissolve in water because they do not have polar molecules that can interact with the water molecules. Nonpolar substances, like oil, do not mix with water because water is a polar molecule and can only dissolve other polar or ionic substances. Additionally, the intermolecular forces between the solute and solvent may not be strong enough to overcome the forces holding the solute together.
Why is beewax not soluble in water less soluble to ethanol and very soluble in chloroform?
Beeswax is a nonpolar substance and water is a polar solvent, so they are not compatible. Ethanol, being able to dissolve both polar and nonpolar substances, can dissolve a small amount of beeswax. Chloroform, being nonpolar like beeswax, allows for better solubility due to similar intermolecular forces.
What Substances that can freely dissolve through the plasma membrane are made of?
Substances that can freely dissolve through the plasma membrane are generally small and nonpolar molecules, such as oxygen, carbon dioxide, and ethanol. These molecules are able to pass through the lipid bilayer of the plasma membrane without requiring a specific transport protein.
Would petroleum ether dissolve in vegetable oil?
Petroleum ether is a nonpolar solvent, while vegetable oil is a nonpolar substance. Since like dissolves like, petroleum ether should be able to dissolve in vegetable oil to some extent.
Why are two non polar substances able to dissolve each other?
Because it is non-polar itself.Remember the addage : Like Dissolves Like.Polar solvents dissolve polar solutes. And non-polar solvents dissolve non-polar solutes.
Are non polar molecules soluble in water?
No.Water can't dissolve non-polar molecules. Water is a polar molecule. Since polar molecules can only dissolve with polar molecules, and non-polar molecules can only dissolve with non-polar molecules, water and non-polar molecules don't react together. Exception:- Some very small non-polar molecules can dissolve in water, like oxygen (O2)
What substances is able to dissolve?
A solvent dissolves things is a solvent, which is dissolving the solute.
