When NaCI dissolves in water does it give ions or molecules or both?
Ions. NaCl is a molecule. And when put in water the polar quality of the water molecules pull apart the na and the cl into ions.
Is a distilled water a polar or nonpolar?
Ionized water means that there are ions in a solution of water. Water itself, whether alone or floating with ions, will always be polar. Other ions or molecules don't affect water's polarity without changing the compound, in which case it will no longer be water.
What can across the membrane with assistance?
large or polar molecules such as proteins, glucose or ions like Na+/K+
How do ions differ from nonpolar molecules?
ions it may be positive charge or negative but nonpolar is having same charge like H2 IS NONPOLAR AND HCL IS POLAR............
Why do acids or bases dissociate?
polar water molecules pull apart the acid or base by pulling on the charged ions.
Do polar molecules have ionic bonds?
Polar molecules typically do not conduct electricity as well as ionic molecules. This is because charges in polar molecules due to unequal sharing of electrons are not as strong as the charges on ions
Which substances passes most readily into a cell ions large molecules glucose carbon dioxide or polar molecules?
Ions
What types of molecules dissolve easily in water?
Polar molecules and ions dissolve easily in water
Do polar molecules conduct energy as well as ionic molecules explain?
no, because there are no ions present.
When NaCI dissolves in water does it give ions or molecules or both?
Ions. NaCl is a molecule. And when put in water the polar quality of the water molecules pull apart the na and the cl into ions.
What causes a base to dissociate?
The polar water molecules pull on the ions of the base.
What molecules would be most likely to pass through the lipid bilyer of a plasma membrane?
ions and polar molecules
What type of solute molecules may be moved by diffusion?
Many polar molecules and ions with the assistance of transport proteins.
Is fat polar?
Fats and oils are nonpolar, so they will remain separate from molecules of a polar solvent such as water. Sodium and chloride ions are attracted to charged regions on molecules of polar solvents such as water.
Why do Ions and polar molecules require transport proteins to enter or leave a cell?
Not necessarily. It helps to be polar because the lipid bilayer is polar and it helps to pull molecules through, but if its a molecule that the cell doesn't want it wont pull it through. Water (a polar molecule) can go through the membrane anywhere but other nutrients need the help of transport proteins.
What types of solute molecules may be moved by facilitated diffusion?
Many polar molecules and ions with the assistance of transport proteins.
What is a dissolved molecule or ion?
In water, which is a polar molecule, ions care surounded by water molecules depending on the charge of the ion. Positive ions form eletrostatic interactions with the oxygen in water and negative ions, with the hydrogens. Polar molecules are easily dissolved in water because they form hydrogen bonds, sort of the same principle behind the interactions that happen between ions and water molecules.
