The reaction N2 (g) + 3H2 (g) → 2NH3 (g) shows an increase in entropy because it involves an increase in the number of gaseous molecules from 2 to 4. Therefore, the entropy change for this reaction is positive.
Reaction D would result in decreased entropy, as the solid reactant (MgCl2) is breaking into ions in solution, which typically decreases entropy. The other reactions involve gases as reactants or products, which generally increase entropy due to higher degrees of freedom in gaseous states.
n2(g)+3H2(g)>2NH3(g)
There are 2 nitrogen atoms in 2NH3.
The reaction is the decomposition of ammonia gas into nitrogen gas and hydrogen gas. The reaction is endothermic, as indicated by the positive value of ΔH (160.58 kJ). This means that heat is absorbed from the surroundings for the reaction to occur.
D MgCl2(s) Mg^2+(aq) + 2Cl^-(aq) would result in decreased entropy, since a solid compound breaking into its ions in solution typically decreases entropy.

The formula for the decomposition for ammonia would be 2NH3 --> N2 + 3H2
There are 2 nitrogen atoms in 2NH3.
2NH3 + 2NA = 3H2 + NA3N2

The balanced equation for this reaction is: N2(g) + 3H2(g) → 2NH3(g).
The bond of reactants that is broken in 2NH3 is the nitrogen-hydrogen (N-H) bond.
The balanced symbol equation for the formation of ammonia is: N2 + 3H2 → 2NH3
the haber process the haber process the equation is N2 + 3H2 <--> 2NH3 the haber process! its easy, the equation is N2 + 3H2 <--> 2NH3
