What is a result of the unequal electron sharing in a water molecule?
alina1380 [7]

Answer:

The right choice is  c. Water molecules have a weakly positive hydrogen end.

Explanation:

The unequal sharing of electrons in water molecule gives a slight negative charge near its oxygen atom ( see image below) and a slight positive charge near its hydrogen atoms. A neutral molecule that has a partial positive charge at one end and a partial negative charge at the other, it is a polar molecule.

so

a. Water molecules have a nonpolar bond.

It is wrong choice because water has polar bond .

b. Water molecules have a weakly positive oxygen end.  

Also, a wrong choice due to water molecule gives a slight negative charge near its oxygen atom.

c. Water molecules have a weakly positive hydrogen end.  

This is the right choice.

d. Water molecules have two oxygen and two hydrogen atoms

It is wrong choice because water has one oxygen and two hydrogen atoms

So, the right choice is

c. Water molecules have a weakly positive hydrogen end.

What is the oxidation state of S in so ??​
Marina86 [1]

Answer:

+2

Explanation:

If a compound SO existed, we would identify the oxidation state of sulfur using the following logic:

  • oxygen is more electronegative than sulfur, so it's more electron-withdrawing and it should have a negative oxidation state producing a positive oxidation state for sulfur;
  • oxygen typically has an oxidation state of -2;
  • we may then apply the fact that SO is expected to be a molecule with a net charge of 0;
  • if the net charge is 0 and the oxidation state of oxygen is -2, we may set the oxidation state of S to x;
  • write the equation for the net charge of 0 by adding all individual charges of the two atoms: x + (-2) = 0;
  • hence, x = 2.

That said, in this hypothetical compound S would have an oxidation state of +2.
