How far from the nucleus in angstroms (1 Å = 10-10 m) is the electron in a hydrogen atom if it has an energy of -8.72 * 10-20 J?

.) the observation by semmelweis that more mothers died of childbed fever when their doctors also worked in the morgue

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
