Answer: The bond of molecule AB is then best described as a covalent bond
Explanation: The bond molecule AB is covalent because the difference in their electronegativity is not very big
Answer:
The pOH is 5.5
Explanation:
pH is defined as the negative logarithm of the concentration of hydrogen ions.
Thus,
pH = - log [H⁺]
The expression between pH and pOH at is shown below as:-
pH + pOH = 14
Given that, pH = 8.5
So, pOH = 14 - 8.5 = 5.5
<u>The pOH is 5.5</u>
It's atomic number is 79 and it's atomic mass is about 196.967

Answer: The shape of a molecule is dependent on the arrangement of the terminal atoms around the central atom.
Explanation:
In the VSEPR, the terminal atoms are treated as electron pairs arranged around the central atom in such a way as to minimize repulsion between them. The number of terminal atoms around the central atom are counted as the electron pairs. Our major concern is how these electron pairs arrange themselves around the central atom.
