Complete the following reactions:(i) CaCO3 (s) + 2HCl(aq) →(ii) SiO2 + 2NaOH →(iii) Fe2O3 (s) + 3CO(g) \(\overset{\Delta}{\rightarrow}\)(iv) C(s) + H2O(g) \(\overset{473-1273K}{\rightarrow}\)(v) 2C(s) + O2 (g) + 4N2 (g) \(\overset{1273K}{\rightarrow}\)

Answer»

(i) CaCO₃ (s) + 2HCl(aq) → CaCl₂ (aq) + CO₂ (g) + H₂O(l)

(ii) SiO₂ + 2NaOH(g) → Na₂SiO₃ + H₂O

(iii) Fe₂O₃ (s) + 3CO(g) \(\overset{\Delta}{\rightarrow}\) 2Fe(s) + 3CO₂(g)

(iv) C(s) + H₂O(g) \(\overset{473-1273K}{\rightarrow}\) CO (g) + H₂(g)

(v) 2C(s) + O₂(g) + 4N₂(g) \(\overset{1273K}{\rightarrow}\) 2CO(g) + 4N₂(g)
