Question

Give the reactions of the conversion of aluminium carbide into methane.?

Answer 1

Heya! Your answer goes like this.

[4Al + 3C → Al₄C₃]

In­ter­ac­tion of alu­minum ox­ide with car­bon at a tem­per­a­ture of 1800 °С.

{2Al₂O₃ + 9C → Al₄C₃ + 6СО}

Al3C4 is a salt-like car­bide, which is es­sen­tial­ly the prod­uct of the dis­place­ment of the hy­dro­gen atom in meth­ane by met­al atoms. So in its hy­drol­y­sis, re­verse dis­place­ment takes place eas­i­ly, and meth­ane forms.

Equa­tion of the hy­drol­y­sis of alu­minum car­bide:

{Al₄C₃ + 12H₂O → 4Al(OH)₃ ↓+ 3CH₄ ↑}

The hy­drol­y­sis of alu­minum car­bide is an ir­re­versible re­ac­tion.

Hope the answer helps you!

Thank you!

All the best.

Answer 2

Hey...!! :)
____________
____________

Di­rect in­ter­ac­tion of car­bon with alu­minum in arc fur­naces:

4Al + 3C → Al₄C₃

In­ter­ac­tion of alu­minum ox­ide with car­bon at a tem­per­a­ture of 1800 °С.

2Al₂O₃ + 9C → Al₄C₃ + 6СО

Hy­drol­y­sis is a re­ac­tion that takes place be­tween a sub­stance and wa­ter, as a re­sult of which the sub­stance and wa­ter break down, and new com­pounds form. Al3C4 is a salt-like car­bide, which is es­sen­tial­ly the prod­uct of the dis­place­ment of the hy­dro­gen atom in meth­ane by met­al atoms. So in its hy­drol­y­sis, re­verse dis­place­ment takes place eas­i­ly, and meth­ane forms.
