properties of water POGIL 1. 2 how many hydrogen molecules in water 2. 1 how many oxygen atoms in water 3. covalent bond what holds the hydrogen atoms to the oxygen atom in water 4. more dense around the oxygen atom than the hydrogen atom in water, where is it more dense 5. oxygen atom where is the majority of negative charge in water molecule 6. covalent bonds what bond is between hydrogen and oxygen in a water molecule 7. weak attraction what kind of attraction is between the hydrogen atom of one water molecule and the oxygen atom of another water molecule 8. oxygen atom and less dense around the hydrogen atoms electrons in a water molecule are more dense around the 9. negative what kind of charge would the oxygen atom have compared to the hydrogen atom 10. positive what kind of charge would the hydrogen atoms have compared to the oxygen 11. the hydrogen atom is attracted to describe the arrangement of the water the oxygen atom of the other water molecules with one another molecule 1/2 12. opposite charges attract one anoth- describe the cause of attractions beer tween molecules of water 13. h+ charge in new molecule attract- if another water molecule was added ed to o- charge in existing molecule to the group, where would it be placed because hydrogen has a positive charge 14. one strand has a slightly positive predict how the two strands are attractarea and one strand has a slightly ed to one another negative area 15. even distribution of electrons what arrangement of electrons would result in a nonpolar molecule 16. they don't interact- they separate w/o mixing how do these (fats oils waxes) nonpolar molecules interact with water 17. the water molecules are attracted to each other and aren't attracted to oil-- they push oil out and pack tightly together why do oil and water interact the way they do 2/2
