8.2 14,5 g of iron reacts with 12 g of water during a corrosion reaction to form Fe3O4 and H2, according to the following equation.

Fe + H2O + Fe3O4 + H2

8.2.1 Balance the equation.

8.2.2 Find the substance which is the limiting reactant? Show your
calculations.

8.2.3 Using the calculations in your answer to Question 8.2.2, determine
the mass of Fe3O4 that will be formed.​

The reaction 2kalsi3o8 + 2(h+ + hco3-) + h2o  →  al2si2o5(oh)4 + 2k+ + 2hco3- + 4sio2 shows that feldspar kalsi3o8 is chemically altered by hydrolysis to form chalky-looking clay mineral kaolinite al2si2o5(oh)4. the chemical breakdown of potassium feldspar due to exposure to acidic water results to the mineral binding with the water molecule to become kaolinite with silica and potassium and bicarbonate ions in solution.
