Write out the chemical equations showing how a buffer solution made from H2PO4- and HPO42- would react to the addition of an acid (H+ ions) or a base (OH- ions). Why is a buffer able to resist pH changes but a solution from a neutralization reaction cannot?

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.

people flirt to show their affection towards someone in a less forward way then telling. they want the other person to guess what they’re feeling to have the other person also start to like them

the mass of the cathode increases because ions from the solution get reduced to atoms and become part of the cathode.
