In chemical weathering of rocks, the equation Fe,2O3+3H2O → Fe2O33H2O represents
Answer Details
The chemical equation Fe2O3 + 3H2O → Fe2O3•3H2O represents the process of hydration, which is a type of chemical weathering. In this process, water molecules combine with the iron oxide (Fe2O3) in the rock to form a hydrated iron oxide compound (Fe2O3•3H2O). This process can cause the rock to expand and weaken, making it more susceptible to erosion. Therefore, option (B) hydration is the correct answer.
