In the complete hydrolysis of of Beryllium carbide (), how many moles of methane () gas are evolved? — s Block Elements Chemistry Question

💡 Solution & Explanation

Demonstrating its diagonal relationship with Aluminium, Beryllium carbide reacts with water to yield methane. The balanced equation is $Be_2C + 4H_2O \rightarrow 2Be(OH)_2 + CH_4 \uparrow$. Thus, $1 \text{ mole}$ of $Be_2C$ produces $1 \text{ mole}$ of $CH_4$.
