week1)Water, Acids, and Bases

Question 1

Cohesion

Answer 1

tendency for the same type of molecules to stick together due to intermolecular forces

Question 2

Why water is cohesive?

Answer 2

• Becuase of their polarity and ability to form hydrogen bonds

Question 3

Oxygen atom with a partial negative charge in one water can bind to?

Answer 3

a hydrogen atom with a positive charge in another water molecule forming a hydrogen bond

Question 4

Each water molecule can form up to?

Answer 4

4 hydrogen bonds with other water molecules

Question 5

Stronge attraction to water molecules becuase of hydrogen bonds can cause?

Answer 5

pull unwards- which generates surface tension- due to this the surface of water can resist rupture- small objects can float- as long as they don’t break the cohesive forces on the surface
