A group of scientists is conducting an investigation to study the conductivity of
perovskite. At which temperature do they need to perform the experiments for
perovskite to conduct electric current?
A. T = 1980°C
B. T > 1980°C
C. T 21980°C
D. T< 1980°C

Of course: ) what’s your name ?

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.
