Calculate the pH of a solution of ammonium acetate. Given that: Ka= 2.25×10–4, Kb= 2.4×10-4and Kw= 1.0×10–14.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

level 4 to level 2 : ))
