On the basis of electronegativity, which of these pairs of elements is most likely to form polyatomic ions?
Vinvika [58]
Correct Answer: <span>O and P

Reason: 
The nature of bond depends on the electronegativity difference of constituent atoms. If difference in electronegativity of constituent atoms is more, it will result in ionic bonding. Alternatively, if difference in electronegativity of constituent atoms is less, it will prefer covalent bonding. Further,  covalently bonded </span><span>elements are most likely to form polyatomic ions.

In present case, electronegativity difference of O and P is minimum. Hence, they </span><span>are most likely to form polyatomic ions.</span>

If the pOH of a nitric acid (HNO3) solution is measured as 11, what is the concentration of HNO3 solution?
Illusion [34]

1 gram of HNO3 will be equal to 1/63.01 moles. Therefore, we can say that 1 liter of Nitric acid contains 15.6976 moles or in other words molarity of 70% (w/w) Nitric acid is equal to 15.6976 M.

Known values  

Molecular weight of HNO3 63.01 g/mole

Concentration of Nitric acid 70% (% by mass, wt/wt)
