Property in which hydrogen bonding causes water molecules to stick together
What is cohesion
100
Considered "the solvent of life"
What is water
100
A bond that occurs when an electron has been donated/accepted
What are ionic bonds
100
Isomers that have different covalent arrangements
What are structural isomers
100
-OH
What is a hydroxyl group
200
Bonds within a water molecule
What are polar covalent bonds
200
In a solution of salt water, salt is the _____
Solute
200
How many bond(s) can one molecule of carbon make? Why?
Four; Four valence electrons, needs four more to make eight
200
For this type of isomer, two large atoms are located on opposite sides of a double bond. (spatial arrangement)
What is a trans isomer
200
Functional groups are ______ in their relation with water.
Hydrophillic
300
Explain how heat must be absorbed/released in the making/breaking of hydrogen bonds.
Heat must be absorbed to break hydrogen bods; heat is released when hydrogen bonds are formed
300
Explain in depth why ice floats
Water molecules form four stable hydrogen bonds with four other water molecules when frozen. When liquid, these bonds are not as stable and molecules can move freely. These means => ice is less dense, water is more dense.

How many electrons are in chlorine's second electron shell?
eight
300
If two molecules have the same molecular formulas, what type of isomer(s) can they be?
Structural, enantiomers, or cis-trans
300
Carobxyl groups are ______ in water
Acidic
400
A compound has a specific heat of 0.45. Will it heat up faster, slower, or at the same speed as water? Why?
Faster, less heat needed to heat 1 gram by 1 degree Celsius

If a person's blood was at a neutral pH, large/small amount of H+/OH- ions would be needed in his or her blood
Small, OH-
