This would be 'chemical' weathering.
Acid rain would react with the minerals in the rocks, causing them to break down.

Answer:
Molecular formula = S₂O
₆
Explanation:
Given data:
Empirical formula = SO₃
Molecular formula = ?
Molecular mass = 152 g/mol
Solution:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Empirical formula mass = 80 g/mol
n = 152 g/mol / 80 g/mol
n = 2
Molecular formula = n (empirical formula)
Molecular formula = 2(SO₃)
Molecular formula = S₂O
₆
Data Given:
% w/w = 5 %
Solution weight = 1500 g
Solute weight = ?
Formula Used:
% w/w = (Mass of Solute / Mass of Solution) × 100
Solving for Mass of Solute,
Mass of Solute = (% w/w × Mass of Solution) ÷ 100
Mass of Solute = (5 × 1500 g) ÷ 100
Mass of Solute = 75 g K₂SO₄
