What type of bond holds a water molecule together?
Polar covalent bond
Why do polar covalent bonds hold a water molecule together?
Due to an uneven distribution of electrons
What type of bond holds one water molecule to another?
Hydrogen bond
What's another thing to call water?
Universal solvent
Is walking on water possible?
No
Due to an uneven charge distribution h20 is unique because...
Of cohesion
Adhesion
And it's a universal solvent (many things dissolve in water)
What is cohesion?
When things are attracted to each other
What is adhesion?
When things stick to other things
What does adhesion have I do with water?
Water has the ability to stick to other surfaces (in a meniscus)
What does cohesion have to do with water?
Water molecules are attracted to each other
Explain how you can prevent breaking surface tension
By distributing weight evenly
What is h20 + ice tea mix = iced tea an example of?
Solution
What is the solvent in the example:
h20 + ice tea mix = iced tea
Water
What is the solute in the example :
h20 + ice tea mix = iced tea
Iced tea mix
What is a solute?
The thing that gets dissolved
What is a solvent?
The things that dissolves
2 or more elements/compounds mixed together but not chemically combined
A mixture
Give 3 examples of a mixture
Salad
Trail mix
Oil and vinegar
What do all organic things contain?
Carbon
What does not have carbon?
Inorganic compounds
Why is carbon a unique element?
The 4 stable single covalent bonds
The ability to form chains
The 2 stable double covalent bonds
How do you find out if something is a carb?
The H:O ratio is 2:1
How can you tell if something is a lipid?
It has a ratio greater than 2:1 of H:O
How can you tell if something is a protein?
N
What are the four groups of organic compounds

Disaccharides
Polysaccharides
Monosaccharides formula
C6 H12 O6
What is sugar found in milk?
Galactose
What does monosaccharides mean?
One sugar
It is found in fruit
Fructose
What do all of the monosaccharides have in common?
Molecular formula
How are the monosaccharides different?
Their structure
Same molecular formula but a different structure is...
Isomers
What does disaccharides mean?
Double sugar
2 monosaccharides chemically bonded together and a H2O molecule is lost is called...
Dehydration synthesis
What is the Molecular formula for disaccharides?
C12 H22 O11
Glucose + fructose = ?
Sucrose and water
Glucose + galactose = ?
Lactose and water
Glucose + glucose =?
Maltose and water
What is sucrose?
Table sugar
What is the sugar found in dairy?
Lactose
Sugar used to make beer
Maltose
What does synthesis mean?
To make
What does dehydration mean?
To lose H20
The C-O-C bond that is formed in a dehydration synthesis reaction
Glycosidic bond
What do you have to do for a dehydration synthesis?
You have to join it where the OH is, remove water from OH
Breaking down of something by the addition of H20
Hydrolysis
Many sugars made of 1000's of monosaccharides
