What is the formula of hydrolith?

  • A
    $\mathrm{MgH}_{2}$
  • Correct answer
    B
    $\mathrm{CaH}_{2}$
  • C
    $\mathrm{BaH}_{2}$
  • D
    $\mathrm{BeH}_{2}$

Solution

$\mathrm{CaH}_{2}$ The hydrolith formula is $\mathrm{CaH}_{2}$. Calcium hydride is a salt-like binary molecule $\left(\mathrm{CaH}_{2}\right)$ that is employed as a reducing agent and a source of hydrogen.
