Phosphorous Oxide
Sulfur trioxide has a trigonal planar molecule.
Carbon trioxide is not a stable chemical compound.
The chemical with the formula N2O3 is called Dinitrogen trioxide.
Strontium Bromide = SrBr2 Sultur trioxide = S03
K3P is actually Potassium Phosphide, not to be confused with Potassium Phosphate.
Sodium and Potassium
Balanced:2 KOH + SO3 ----> K2SO4 + H2O
This is a so-called 'solid-gas' reaction K2O(s) + SO3(g) --> K2SO4(s)
