Answer:
9.92
Explanation:
Since we are given the concetration of H+ we can find the ph by taking the negative log and then subtracting the ph from 14 to give us pOH
-log(8.26e-5) = pH= 4.08
pOH= 14-4.08
pOH= 9.92
The noble gas configuration system helps to shorten the total electron configuration by using the symbol for the noble gas that lies before the particular element in the periodic table.
For example:
Na has atomic number 11
Electron configuration of Na: 1s2 2s2 2p6 3s1
Noble gas electron configuration of Na: [Ne] 3s1
Ne has atomic number 10 and lies before Na in the periodic table.
In an ionic bond, one atom essentially donates an electron to stabilize the other atom. The atoms in an ionic bond have different electronegativity values from each other.
While in a covalent bond, the atoms are bound by shared electrons and the electronegativity values are the same.
Just use q=mCDeltaT
q=energy
m=mass
c=specific heat
Delta T= Change in temperature
