Cell Compounds / Properties Of Water Flashcards
what is an inorganic molecules
contains metals and non metals ( ionic )
composed of small atoms and is non living
ex. NaCl, H2O, CO2
What is an organic molecule
Covalent
Contains C and H ( may contain metals )
Large amount of atoms and living
Ex. Complex Molecules like Proteins such as hemoglobin
What type of molecule is Water
Polar Covalent Inorganic
What does multiple H Bonds do to water molecules
It results in high melting and boiling points. Water has a high heat capacity
Weak forces that attract ( and hold ) opposite dipoles of a molecule are called?
Hydrogen Bonds
What is Adhesion
Attraction between water molecules on a foreign surface ( water creeping on the edge of a glass)
What is Cohesion
Force between Water Molecules of 2 water molecules together ( 2 raindrops combining by pulling on each other).
This causes surface tension
What do Emulsifiers do
Emulsifiers: suspend one liquid in another ( oil and water )
What emulsifiers are in your body and why are they important
Bile, breaks up fat into smaller pieces / blobs
What properties of water result in its polarity
Adhesion
Multiple H Bonds causing High Boiling Point
Are acids and bases ionic or covalent
Acids are Covalent
Bases are Ionic
What is Surface Tension
When Cohesion Happens this results in the 2 drops of water combining giving it higher surface tension. This results in bugs being able to stand on water
What makes Acids Acidic
Acids are H+ Donators and release H+
What makes Bases Basic
They are H+ Acceptors and Release OH-
What happens when you mix acid and bases, what is the product
They become neutral transforming into salt and water
