Chlorine atom differs from chloride in the number of which of the following?
Protons
Neutrons
Electrons
Both (a) and (c)
In the following reaction,
P4 + 3NaOH + 3H2O → PH3 + 3NaH2PO2
phosphorus is oxidised
phosphorus is oxidised and reduced
phosphorus is reduced
sodium is oxidised
B.
phosphorus is oxidised and reduced
P4 + 3NaOH + 3H2O → PH3 + 3NaH2PO2
In this reaction, oxidation number of phosphorus is changing from zero to -3 and zero to +1. Hence both oxidation and reduction of phosphorus takes place.

ammonium nitrate coating on the metal
a thin oxide layer coating on the metal
a hydride coating on the metal
