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?
What's another thing to call water?
Is walking on water possible?
Due to an uneven charge distribution h20 is unique because...
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?
What is the solvent in the example:
h20 + ice tea mix = iced tea
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
Give 3 examples of a mixture
Oil and vinegar
What do all organic things contain?
What does not have carbon?
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?
What are the four groups of organic compounds
What are carbohydrates made up of?
Carbon, hydrogen, and oxygen
What is the ratio for hydrogen and oxygen
What do carbohydrates usually end in?
What are the three main groups of carbohydrates?
C6 H12 O6
What is sugar found in milk?
What does monosaccharides mean?
It is found in fruit
What do all of the monosaccharides have in common?
How are the monosaccharides different?
Same molecular formula but a different structure is...
What does disaccharides mean?
2 monosaccharides chemically bonded together and a H2O molecule is lost is called...
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?
What is the sugar found in dairy?
Sugar used to make beer
What does synthesis mean?
What does dehydration mean?
To lose H20
The C-O-C bond that is formed in a dehydration synthesis reaction
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
Many sugars made of 1000's of monosaccharides
Used by plants to store excess sugar
Give an example of starch
Excess sugar is stored in the liver and muscle cells of animals
Primary component of wood and plant cell walls. It's indigestible by humans
What's an example of cellulose?
What are the three Monosaccharides?
Where is glucose found?
in sugar plants
What are the three Polysaccharides?
What are the three Dissaccharides?
How many things can carbon bond with?
How many things can Oxygen bond with?
How many things can Hydrogen bond with?
Made of glucose monomers joined together
