Means it had a factory repair in June of 39 or 61 which would be a guess, but based on the serial it could become obvious.
The hybridization of PH3 is sp3
PH3 is an acid.It is a flammable substance.
pH3. It is more acidic
PH3 has a higher vapor pressure than NH3 because the PH3 has weaker attractive forces. Therefore, PH3 also boils lower than NH3.
Neither PH3 nor NH3 are acids. They are both bases. NH3 is the stronger base
This is ammonia, NH3.
Yes
A PH3 molecule contains 4 atoms: 1 phosphorus and 3 hydrogen.
It is technically PH3, and it is called Phosphine
P3+
Ph3 is acidic. Equivalent to lemon juice. Ph0 is super acidic and 7 is neutral.
With traces of P2H4 present, PH3 is spontaneously flammable in air
