Periodic Table, Atomic Structure & Types of Bonds

The tendency of water droplets to stick to each other is...

• ahesion

• capillary action

• surface tension

• cohesion

Why is water considered to be a polar molecule?

• Oxygen has a slightly positive side and hydrogen has a slightly negative side.

• The carbon makes the hydrogen bond with calcium.

• Water is not polar, it is nonpolar like oil.

• Oxygen has a slightly negative side and hydrogen has a slightly positive side.

What is adhesion?

• attraction between two different molecules

• attraction between the same molecules

• when a substance dissolves into another substance

• another word for molecules

TRUE or FALSE: the cohesive attraction of molecules to molecules are due to INTERMOLECULAR forces.

• TRUE

• FALSE

What is cohesion?

• attraction between two different molecules

• attraction between the same molecules

• when a substance dissolves into another subsubstance

• another word for molecules
