Al2(SO4)3 would be the formula.
Weathering of the rock and sedimentation are decomposition processes. Through time, the minerals in the rocks soften due to pressure and heat. So, they crumble down and reduce in terms of size. Once they do, they become sand or part of the soil. So, the answer is A.
The answer is true, particles in the gaseous state are the furthest apart
Maybe gas? because you can’t see it and it’s formed during a chemical reaction
