How do H2O molecules differ from most molecules? OA. They contract when cooled to 0°C.
OB. They expand when cooled to 4°c.
C. They expand when cooled to 0°C.

"electrical energy" transforms to "thermal energy".hope my answer has you : )

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.

The answer is:   [d]:   "ultraviolet" {"  uv  "} .
