[H+][OH-]=10-¹⁴
We are using this formula because we need to find the H+
substitute the value given for hydronium ion for OH-
[H+][4.19×10⁵]=10-¹⁴
[H+]=10-¹⁴÷4.19×10⁵
[H+]=2.387×10-¹⁹
Then the pH of the solution will be
pH= –log¹⁰ [H+]
pH = –log¹⁰ [2.387×10-¹⁹]
pH= –log¹⁰2.387+19log¹⁰
= –0.378+19
pH =18.622
Answer:
3N2Cl4 + 3CH4--> 3CCl4 + 3N2 + 6H2
This simplifies to:
N2Cl4 + CH4 --> CCl4 + N2 + 2H2
D.) "Vaporization" <span>is not a form of heat transfer.
It is just conversion of the state of matter from Liquid to Vapor

Answer:
Energy levels 4-7
Explanation:
The energy levels in an atom are shown by the principal quantum number (n). Typically, the d orbitals begins to occur from the third energy level through the seventh energy level.
Most second and third row d-block elements are found between energy level n=4 and energy level n= 7 in the periodic table. Hence the answer
