What is a result of the unequal electron sharing in a water molecule?
Katarina [22]

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

<u>So, the right choice is</u>

c. Water molecules have a weakly positive hydrogen end.

a compound consists of 17.6% of hydrogen and 82.4% nitrogen. Determine the empirical formula of the compound
Wewaii [24]
17,6% + 82,6% = 100%

mass of N = 14g
mass of H = 1g

17,6% H = 17,6g H
82,4% N = 82,4g N

17,6g : 1g = 17,6  moles of H
82,4g : 14g = 5,89 moles of N

N  :  H  =  5,89  :  17,6  ||:5,89
N  :  H  =  1      :   2,99≈3

the empirical formula of the compound = NH₃  (ammonia)
