answer
Two
question
How many oxygen atoms are in a molecule of water?
answer
One
question
What holds the hydrogen atoms to the oxygen atom?
answer
Covalent bond
question
Where is the majority of negative charge on the water molecule?
answer
Oxygen
question
What kind of charge would the oxygen atom have compared to the hydrogen atom?
answer
Higher negative charge
question
What kind of charge would the hydrogen atoms have compared to the oxygen?
answer
Higher positive charge
question
Non polar molecules
answer
Some molecules that are covalently bonded do not have a difference in charge across the molecule
question
What arrangement of electrons would result in a nonpolar molecule?
answer
The bonding in the molecules have to be equally shared between the atoms
question
Some examples of nonpolar molecules include fats, oils, and waxes. How do these substances interact with water?
answer
They cannot mix
question
What prediction would you make about why oil and water interact?
answer
The bonding in electrons in the molecules are equally shared. Polar and nonpolar do not mix.
question

answer
More dissolved stuff; less water
question
