Answer 2

Water has a dipole moment. When two atoms in a chemical bond differ in their affinity for electrons, the shared electrons spend more time around the atom that pulls hardest on those electrons. Because the electron spends more time close to that atom, that atom picks up a partial negative charge and its bonding partner - the one with the lower affinity and weaker pull on the electron - picks up a partial positive charge.

Answer 3

thx can u help with one more

Answer 4

Sure.

Answer 5

xamine the water molecule pictured below and answer the following questions:
The bonds holding this molecule together are covalent bonds. What have you learned about covalent bonds?

Answer 7

Indeed the intramolecular bonds in water molecules - the bonds between the oxygen and hydrogens of the same water molecule - are covalent. But I have no idea what you have or have not yet learned about covalent bonds.

Answer 8

srry ilied i need 2

Answer 9

I'm sorry, I don't understand - you need two of what?

Answer 10

i have 2 more questions

Answer 11

Ah.

Answer 12

Examine the water molecule pictured below and answer the following questions:
How do you think water molecules would bond to other polar molecules?

Answer 14

So in the first question we established that the oxygen atom carries a partial charge and the hydrogen atoms carry a partial opposite charge. Is that much clear?

Answer 15

so its just the oppisite

Answer 16

The charge across a single water molecule is opposite, yes. So when you think about two water molecules, each with a partial charge across it, opposite charges attract each other. Think about the implications for how two separate water molecules orient themselves relative to each other.

Answer 17

ooh ok

Answer 18

so how could i write it in my own words

Answer 19

wait i got

Answer 20

Examine the water molecule pictured below and answer the following questions:
The part nearest the oxygen end of the molecule has what kind of charge?

Answer 21

Answer 22

Is the charge on the oxygen atom positive or negative?

Answer 23

negative

Answer 24

You just answered your own question - the oxygen atom has a partial negative charge.

Answer 25

oooh hahah i was over thinking it thx @blues

Answer 26

u deserve 2 medals

Answer 27

Thanks. Glad to be helpful.
