MgCl2 + N2 = Mg3N2 + 3 Cl2
n2 = 20 + n so n2 - n - 20 = 0 that is (n - 5)(n + 4) = 0 so that n - 5 = 0 or n + 4 = 0 n = 5 or n = -4

Absallutly!
n=40 n2+n+41=1681 which is not a prime.
Endothermic
Mg + MgCl2
The reaction that would result in decreased entropy is N2 + 3H2 → 2NH3.
No reaction

n2 + n2 = 2 n2
The formula for the synthesis of ammonia from diatomic nitrogen and hydrogen is: N2+3H2-->2NH3
H2CN2 + heat --> N2 + CH2
n2 = 20 + n so n2 - n - 20 = 0 that is (n - 5)(n + 4) = 0 so that n - 5 = 0 or n + 4 = 0 n = 5 or n = -4

The balanced reaction for N2H4 + H2O2 --> N2 + H2O is N2H4 + 2H2O2 --> N2 + 4H2O
n2-3n+2
MgCl2 is formed. Mg2+ + 2Cl- ----> MgCl2
