Question

Aluminium carbide reacts with water according to the following equation :

`Al_4C_3 + 12H_2O-> 4Al(OH)_3 + 3CH_4`

1)What mass of aluminium hydroxide is formed from 12g of aluminium carbide?

2) What volume of methane at s.t.p. is obtained from 12g of aluminium carbide?

[Relatively molecular weight of `Al_4Cl_3 = 144; Al(OH)_3 = 78]`

Solution

1)

So, the amount of 3 Al(OH)3 formed will be 26 gm

2) From 12 gm Al4C3 5600 cc methane will be formed
