blannce the equation like this

Answer 2

$\huge\text{\underline{Answer}}$

Balanced chemical equation

The chemical equation in which the number of atoms in reactants side is equal to the number of atoms on products side.

Balanced chemical equation follow the law of conservation of mass.

$\bold{4Al3 + 9O2 => 6Al2O3}$

$\huge\text{\underline{Verification}}$

Since, the no. of atoms of almunium is 12 on reactant side and also no. of atom of almunium is 12 on product side.

Similarly no. of atoms of oxygen is 18 which is equal to the no. of atom on reactant side.
