According to the chemical reaction 3H2(g)+N2(g)⇌2NH3(g)+energy, the forward reaction can best be described as a(n) :
(i) Displacement reaction (ii) Combination reaction (iii) Redox reaction (iv) Neutralisation reaction (a) (i) and (iv) (b) (ii) and (iii) (c) (i) and (iii) (d) (iii) and (iv)
Identify the types of reactions:-
(i) H2(g) + Cl2(g) → 2HCl(g)
(ii) NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)
(iii) Fe(s) + S(s) heat−−→ FeS(s)
