3NO2 (g) + H2O (l) ↔ 2HNO3 (aq) + NO (g) Jika direaksikan 980 kg gas NO2 dengan 450 liter air, setelah 40 % gas NO2 bereaksi sistim mengalami kesetimbangan. A. Tentukan komposisi senyawa dalam tanki saat kesetimbangan (skor 5) b. Jika volume tanki 1000 liter, tentukan nilai konstanta kesetimbangan Kc (skor 10) c. Jika tekanan total tanki 24 atm, tentukan nilai konstanta kesetimbangan Kp (skor 5)

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.

Theyre semiconductors.
