How do polar molecules form hydrogen bonds?

Polar molecules form hydrogen bonds when hydrogen is bonded to Nitrogen, Oxygen, or Fiorina. This is because these atoms are highly electro-negative meaning they often have the electron they have sharing with hydrogen. Hydrogen atoms bonded with these atoms are attracted to the partial negative charge of similar atoms.

What determines whether a compound will dissolve in water?

Water is a polar molecule and transmits a partial positive and negative change between its atoms, enabling it to easily dissolve other ions and polar molecules.

How do polar molecules differ from non-polar molecules?

Polar molecules have charged regions due to unequal sharing of electrons/ Nonpolar molecules do not have charged regions because electrons are shared more equally. The charge differences tend to keep the molecules separate.

Describe an example of cohesion or adhesion that you might observe in your daily life.

Cohesion: water beading on a surface.

Adhesion: water sticking to the side of glass.

How do polar molecules form Hydrogen Bonds?

The atoms of polar molecules give up electrons to hydrogen atoms. The polar molecules have charged regions that can attract other polar molecules. Hydrogen atoms in water molecules attract each other with positive charges.

What determines whether a compound will dissolve in water?

When polar compounds or ions are added to water, they break up into smaller components, or dissolve, to become part of the solution. The water's partical charges attract different parts of the compound, making the water.

How do polar molecules differ from non-polar molecules?

Polar molecules occur when there is an electronegative difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.

Describe an example of cohesion or adhesion that you might observe in your daily life.

Cohesion is the behavior of water molecules. Each water molecule can form four hydrogen bonds with neighbor molecules. The surface tension produced by cohesion makes it possible for light objects to float on water without sinking.

Adhesion is a property of water and is an attraction that occurs between two different substances such as water and the cell walls of plant cells. An example: a tree needs to be able to transport water over a long distance form its roots to the leaves at the top of a tree.
