Question

Al2O3+HCI---AIC13+ H20*​

Answer 1

We have to balance the equation.

$\boxed{\sf {Al_2O_3\atop Aluminium\:oxide}+{6HCl\atop Hydrochloric \:Acid}\longrightarrow {2AlCl_3\atop Aluminium\:Chloride}+{3H_2O\atop Water}}$

Reactant side:-

• Aluminium=2atoms
• Chlorine=6atoms
• Oxygen=3atoms
• Hydrogen=6atoms

Product side:-

• Aluminium=2atoms
• Chlorine=6atoms
• Oxygen=3atoms
• Hydrogen=6atoms

Hence balanced
