Question

give the equation : 1.prepation of methane from aluminium carbide​

Answer 1

It shows stability up to 1400 °C. It decomposes in water with the production of methane. From the reaction, we can see that 1 mole of aluminium carbide (Al4C3) reacts with 12 moles of water (H2O)to give 4 moles of aluminium hydroxide (Al(OH)3) and 3 moles of methane gas (CH4).
