- What causes the band of color in the mountains? What distinguishes the minerals in this mountain?
- What Causes the colors in a fireworks display?

I would really appreciate the help PLEASE.

What is the question

The correct answer would be b) volume versus temperature, because they are also directly proportional.

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.
