Answer:
option D= Gold (I) nitride
Explanation:
The name of the given compound is gold(I) nitride.
Molar mass can be determine by following way:
molar mass Au3N = (molar mass of gold × 3) + (molar mass of nitrogen)
molar mass Au3N = (196.97 × 3 ) + ( 14 )
molar mass of Au3N = 590.91 g/mol + 14 g/mol
molar mass of Au3N = 604.91 g/mol
The nitrogen has valency of -3 so three Au(+1) will require while the valency of Au is (1+) one nitrogen will require to make the compound overall neutral.
Au3N
3(1+) + (-3) = 0
+3 - 3 = 0
0 = 0
The overall charge is 0, the compound will be neutral.
It does not consist of a single element

Metals higher in the reactivity series may displace least reactive metals from their salts. For example sodium is reactive than copper therefore it would displace copper ions from its salt. In this case, Sodium is more reactive than Magnesium and therefore magnesium cannot displace sodium ions from sodium sulfate , therefore, no reaction will take place.
