There will either be no reaction or the copper would replace the tantalum...
Copper(II)nitride
The formula for copper(I) nitride is Cu3N. Nitride has a valency of -3
if it's copper(II) nitride, then it's Cu3N2 (it's nitride by the way not nitrade)
if it's copper(II) nitride, then it's Cu3N2 (it's nitride by the way not nitrade)
It depends on whether you are talking about copper I or copper II. For copper I nitride the formula is 3Cu+ + N3- -> Cu3N. If it is copper II it is 3Cu2+ + Cu3N2
Copper Nitride Copper Nitrate
Copper(II) Nitride
Metals: tantalum, rhenium, wolfram, osmium Nonmetals: diamond, graphite Compounds: hafnium carbide, hafnium boride, hafnium nitride, tantalum hafnium carbide, etc.
Copper Nitride
The formula may be Cu3N and name is copper nitride.
The formula is Cu(NO3)2 and is called Copper (II) Nitrate. See attached link for more information.
I think the compound supposed to be Cu3N2. The name is Copper (II) Nitride.
