What is the concentration of silver ions where silver iodide, Agl, is in a solution of hydroiodic acid, HI, that has a pH of 3.55? Ksp = 8.51x10-17

Heat is involved in chemical change in two ways; chemical changes either result in heat being added to or removed from an object, and chemical changes require a certain amount of heat before they can take place.

Just took the quiz on edgenuity and the correct answer is "c.  4.54 x  10–12  j"

Oxygen= 88ghydrogen= 12g

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.
