Hope this helps. :)
PH + pOH = 14
11.8 + pOH = 14
pOH = 14 - 11.8
pOH = 2.2
[OH-] = 10 ^- pOH
[OH-] = 10 ^- 2.2
[OH-] = <span>6.33 x 10^-3 M

Answer:
![\frac{15}{7}N](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B7%7DN)
Explanation:
We already know that the mass number of an atom is the sum of the number of protons and the number of neutrons.
So, the mass number of this isotope is;
Number of protons = 7
Number of neutrons = 8
Mass number = 7 + 8 = 15
Hence, the isotope is;
![\frac{15}{7}N](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B7%7DN)
Answer:
There are three atoms in the equation
Answer:
Aluminium oxide has higher melting point than aluminium chloride because there nay be some impurities in the oxide which affects the intermolecular force of attraction
