Fe2O3 + _H2SO4 → _Fe2(SO4)3 + __H2O what are the coefficients

Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O

Explanation:

Step 1: Write out unbalanced reaction

Fe₂O₃ + H₂SO₄ → Fe₂(SO₄)₃ + H₂O

Step 2: Balance

We need the same number of SO₄²⁻ on each side

Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + H₂O

Now we need the same amount of H⁺ on each side

Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
