Water

Question 1

Is water polar or nonpolar?

Answer 1

Water is a polar molecule

Question 2

Hydrophilic

Answer 2

• Dissolve in water
• Polar

Question 3

Hydrophobic

Answer 3

• Do not dissolve in water
• Non-polar
• They do not have any charges

Question 4

Is water a solvent or solute?Why?

Answer 4

Water is a solvent because it is capable of dissolving many different substances.

Question 5

Hydrophobic effect

Answer 5

When polar molecules like water exclude non-polar ones. Leading to the folding of proteins and creating of cell membranes.
