Overall loss in electon = 2-1=1
Answer:
<u>The pH at equivalence is 5.24 .</u>
Explanation:
Let us calculate -
millimoles of aniline = 160 x 0.3403 = 54.448
To reach equivalence , 54.448 millimoles HNO3 must be added,
V = 1086.79 mL HNO3 must be added
total volume = 1086.79 + 160 = 1246.79 mL
Concentration of [salt] = = 0.044 M
Now, at the equivalence or equivalent point ,
By solving the above equation , we get -
pH = 5.24
<u>Hence , the answer is 5.24 </u>
Count how many protons there is and search up what symbol has this many protons
Divide by the atomic mass of iron. Look at your periodic table.

Answer:
Valence electrons are important because they
The electrons that occupy the outer most shell of an atom are called valence electrons. They are important because they determine how an atom will react. By writing an electron configuration, You'll be able to see how many electrons occupy the highest energy level.
