The gage pressure of carbon dioxide in a closed tank is -10 kPa. A mercury barometer gives the local atmospheric pressure is 760 mmHg or 1 atm. Determine the absolute pressure of the carbon dioxide, in kPa.

The answer is true a geyser can reach up to 205 degrees fahrenheit

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.
