What`s the lewis structure for ch3oo?

See the figure 1.

Explanation:

For the acetate ion we will have a formula of . We have to keep in mind that we will have 1 electrons for each hydrogen, 4 electrons for each carbon and 6 electrons for each oxygen and 1 for negative charge.

So, we will have in total:

H=>(1x3)= 3 e-

C=>(2x4)= 8 e-

O=>(2x6)= 12 e-

-1=> 1 e-

Total= 3e- + 8e- + 12e- + 1e- = 24e-  (Figure 2)

When we do the formal charge for each atom we will have:

H=> FC=1-(0+*2)=zero

C=> FC=4-(0+*8)=zero

O=>FC=6-(4+*4)=zero

O=>FC=6-(6+*2)=-1

The total charge of the molecule is -1.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
