Aluminium carbide reacts with water according to the following equation.
\[\ce{Al4C3 + 12H2O -> 3CH4 + 4Al(OH)3}\]
What mass of aluminium hydroxide is formed from 12g of aluminium carbide?
उत्तर
\[\ce{Al4C3 + 12H2O -> 3CH4 + 4Al(OH)3}\]
[4 x 27 + 3 x 12] 4[27 + 17 x 3]
108 + 36 4[27 x 51]
144 g 312 g
Since 144 g of Al4C3 gives 312g of Al(OH)3
So , 12 g of Al4C3 will give = `312/144 xx 12`
= 26 g Al(OH)3
