Question

Write the balanced chemical equation :
(i) ZnO + CO ➝
(ii) C + H₂O ➝
(iii) B₂H₆ + O₂ ➝
(iv) H₃BO₃ ➝
(v) Al + NaOH ➝
(vi) BF₃ + NH₃ ➝

Answer 1

(i) ZnO + CO \(\overset{\Delta}{\longrightarrow}\) Zn + CO₂

(ii) C + H2O \(\overset{473-1273\, K}{\longrightarrow}\) CO + H₂ (Water gas)

(iii) 2H₃BO₃ ➝ B₂O₃ + 3H₂O

(iv) H₃BO₃ \(\overset{370\,K}{\longrightarrow}\) HBO₂ \(\overset{\Delta}{\longrightarrow}\) B₂O₃

(v) 2Al + 2NaOH + 6H₂O ➝ 2Na[Al(OH)₄] + 3H₂

(vi) BF₃ + NH₃ ➝ [B(NH₃)F₃]
