LiH + AlCl3 = LiAlH4 + LiCl

Balanced Chemical Equation – Solution

4LiH + AlCl3 → LiAlH4 + 3LiCl

The coefficients show the number of particles (atoms or molecules), and the indices show the number of atoms that make up the molecule. New substances are formed as a result of the rearrangement of the original atoms. As a result of a chemical reaction, atoms of chemical elements do not disappear anywhere and new ones do not appear, their number remains unchanged – this follows from the law of conservation of mass of substances.
