Well, friend, flour is made up of both polar and nonpolar molecules. You see, flour contains a mix of different molecules like starch and proteins, some of which have polar regions and some that are nonpolar. It's all part of the beautiful balance that makes flour such a versatile and essential ingredient in our creative culinary endeavors.

Is air polar or non polar?
Air is considered nonpolar because it is mostly made up of nonpolar molecules such as nitrogen (N2) and oxygen (O2). Although water vapor can be present in air and is a polar molecule, the overall composition of air is nonpolar.
Is the polar head of a phospholipid made of molecules?
Phosphate molecules.
Why doesnt oil dissolve in ocean water?
Oil is less dense than water and is made up of hydrocarbons that are not soluble in water. The molecules in oil are nonpolar, meaning they do not have a charge to interact with the polar water molecules, so they do not mix well together. This is why oil tends to float on the surface of water rather than dissolve into it.
Does oil have a polar covalent bond?
No. If oil did have a polar covalent bond, that would make it hydrophilic (attracted to water) and oil is hydrophobic (repels water). All the covalent bonds in the hydrocarbon tails are non-polar covalent.
Why does naphthalene dissolve in organic solvents but does not dissolve in water?
naphthalene is only made of two types of atom: carbon and hydrogen. There is little difference in electronegativity between these atoms (how well they can pull on electrons) so there is an equal distribution of electron density across the molecule, thus being NON-POLAR. Water on the other hand is comprised of oxygen and hydrogen atoms, between which there is a large difference in electronegativity. This means that there is an imbalance of charge across the molecule resulting in water being POLAR. a polar molecule is unable to interact with a non-polar molecule as they don't 'have anything in common' in terms of their charge distribution. Naphthalene will dissolve in petrol due to petrol being a non-polar solvent.
Do substances made of nonpolar molecules only dissolve in nonpolar or polar solvents?
Like dissolves like. Polar compounds dissolve in polar solvents and nonpolar compounds dissolve in nonpolar solvents. An exception to this rule, however, is that an electronegative atom can only take four or five carbons into a polar solvent. An alcohol with an alkyl chain seven carbons long, for example, will not be soluble in a polar solvent, even though it is a polar molecule.
Is air polar or non polar?

Is the polar head of a phospholipid made of molecules?
Phosphate molecules.
What do nonpolar molecule have?
Nonpolar molecules have no net dipoles. The most common nonpolar molecules are hydrocarbons. These are molecules made entirely of carbon and hydrogen atoms.
What are emulsions?
A polar and a nonpolar substance being made miscible together by another substance that has both polar and nonpolar characteristics.
Can nonpolar molecules cross the lipid bilayer?
Yes, nonpolar molecules can cross the lipid bilayer because the lipid bilayer is made up of nonpolar molecules itself, allowing nonpolar molecules to pass through easily.
Why doesnt oil dissolve in ocean water?
Oil is less dense than water and is made up of hydrocarbons that are not soluble in water. The molecules in oil are nonpolar, meaning they do not have a charge to interact with the polar water molecules, so they do not mix well together. This is why oil tends to float on the surface of water rather than dissolve into it.
What do nonpolars have?
Nonpolar molecules have no net dipoles. The most common nonpolar molecules are hydrocarbons. These are molecules made entirely of carbon and hydrogen atoms.
What is in a substance that makes it hydrophobic?
Substances are hydrophobic because they are nonpolar. Nonpolar molecules are made up of elements with little difference in their electronegativities so they do not have charges or partial charges. Water is a polar molecule so it tends to be attracted to other molecules that are polar as well. This is often summed up as "like attracts like". Some examples of hydrophobic molecules include fats and oils which are nonpolar because they have large hydrophobic hydrocarbon chains.
Does oil have a polar covalent bond?
No. If oil did have a polar covalent bond, that would make it hydrophilic (attracted to water) and oil is hydrophobic (repels water). All the covalent bonds in the hydrocarbon tails are non-polar covalent.
Why is a lipid bilayer incellmembrane considered as a barrier to the diffusion of polar molecules?
Polar molecules are hydrophilic in nature. They tend to repel from the lipid content and would easily adhere or mix with the water molecules. A lipid bi-layer consists of lipids and so it would not allow the polar molecules to pass through.
