Answer:
In order to attain stability
Explanation:
Every chemical bonds that are formed results from the desires of atoms to achieve stability like the inert and nonreactive noble gases. By so doing, their outer shell electrons must be completely filled to attain an octet configuration like the noble gases with eight outermost electrons.
An atom of oxygen has six outer electrons. To complete its octet, it will require just two more electrons.
This desire will make it bond with another atom. In the vicinity of another oxygen atom, it will bond. The type of bond formed will be a covalent bond which results from each of the oxygen atom sharing two of their valence electrons.
The joint shared electrons will now be four electrons. This four electrons will make each of their octet complete and a covalent bond occurs.

Explanation:
HCl reacts with NH3 as follows:
HCl + NH3 → NH4+ + Cl-
<em>1 mole of HCl reacts per mole of ammonia.</em>
Mass of NH3 is obtained as follows:
<em>Moles HCl:</em>
0.02999L * (0.1068mol / L) = 3.203x10-3 moles HCl = <em>Moles NH3</em>
<em>Mass NH3 in the aliquot:</em>
3.203x10-3 moles NH3 * (17.031g / mol) = 0.0545g.
Mass of sample + water = 22.225g + 75.815g = 98.04g
Dilution factor: 98.04g / 14.842g = 6.6056
That means mass of NH3 in the sample is:
0.0545g * 6.6056 = 0.36g NH3
Weight percent is:
0.36g NH3 / 25.225g * 100
