Aluminium carbide reacts with water according to the following equation :
`Al_4C_3 + 12H_2O rarr 4Al(OH)_3 + 3CH_4`
What mass of aluminium hydroxide is formed from 12 g of aluminium carbide ?

Explanation

To find the mass of aluminum hydroxide (Al(OH)₃) formed from 12 g of aluminum carbide (Al₄C₃), we can follow these steps:

### Step 1: Write the balanced chemical equation
The balanced chemical equation for the reaction is:
\[ \text{Al}_4\text{C}_3 + 12\text{H}_2\text{O} \rightarrow 4\text{Al(OH)}_3 + 3\text{CH}_4 \]

### Step 2: Calculate the molar mass of aluminum carbide (Al₄C₃)
The molar mass of Al₄C₃ can be calculated as follows:
