What else can I help you with?
What is this statement most likely referring to Small nonpolar molecules may pass through this structure but others require a protein channel?
Small non-polar molecules may pass through a a semipermeable membrane but others require a protein channel.
how do you explain what polar molecules are?
Water molecules are polar molecules. Both of the bonds inside the molecule are polar bonds.
What characteristics do all polar molecules share?
Polar molecules have an uneven distribution of electron density within the molecule, resulting in a permanent dipole moment. This is typically due to differences in electronegativity between the atoms in the molecule. Polar molecules are attracted to other polar molecules through electrostatic interactions.
What structure is this statement most likely referring to?
Small non-polar molecules may pass through a a semipermeable membrane but others require a protein channel.
What kind of molecule is Cl2 polar or non polar?
Halogen molecules are not polar.
Is a polar molecule is a molecule with the ability to resists changes in temperature?
A polar molecule is a molecule with slight opposite charges. Water is a polar molecule which means that each water molecule is attracted to other water molecules which accounts for waters surface tension or cohesion.
Are sugars non polar Molecules?
No, sugars are polar molecules considering that they will interact and dissolve in water (which is also a polar molecule). Polar molecules will only interact with other polar molecules and vice-versa.
Molecules that do not have oppositely charged ends are what molecules?
Molecules that do not have oppositely charged ends are nonpolar molecules.
Which Intermolecular force is common to all polar molecules but not non polar molecules?
Dipole-dipole interactions are common to all polar molecules but not nonpolar molecules. This force results from the attraction between the positive end of one polar molecule and the negative end of another polar molecule.
Does a sugar molecule have a polar bond to a gasoline molecule?
No, a sugar molecule does not have a polar bond to a gasoline molecule. Sugar molecules mostly contain polar hydroxyl groups, while gasoline molecules are nonpolar hydrocarbons. Therefore, they do not form polar bonds with each other.
What can not cross the semipermeable membrane?
Large molecules such as proteins and polysaccharides cannot easily cross a semipermeable membrane due to their size. Additionally, charged molecules like ions may have difficulty crossing depending on the membrane's properties. Lipid-soluble molecules, gases, and small uncharged polar molecules can usually pass through more easily.
If a water molecule is neutral why does it attract polar molecules?
Water molecules have a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom, causing it to be a polar molecule. This polarity allows water to form hydrogen bonds with other polar molecules, such as those containing oxygen or nitrogen, leading to attraction between water and other polar molecules.
