So there was a question where I had to write out potassium+water as a chemical equation. So I did: 2K + H2OK2O + H2 But the answer was: 2K + 2H2O2KOH + H2 I asked my sister about this, and she said potassium oxide doesn't exist. But I googled it andit does. So why doesn...
Use atomic or molecular properties to explain why calcium oxide has a much higher melting point (2580 degrees Celsius) than potassium fluoride (858 degrees Celsius). Explain why it is unlikely for magnesium to form a cati...
