When 2.5 moles of PCl₅ is heated in a 1.0 L container, an equilibrium is established which has 0.75 moles each of Cl₂ and PCl₃ present. What is the Keq for the following equation? PCl₅ (g) ↔ PCl₃ (g) + Cl₂ (g) ? A. 3.33
B. 4.44
C. 0.225

What’s the solution?

The correct answer is b) false

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.
