A 26.8 g diamond ring was heated for sizing to 54.3 oF. It is cleaned through sonication in a 205.3 g vat of water at room temperature 21.2 oC. What is the final temperature of both substances at thermal equilibrium

Yes she is correct. the answer is completely correct

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.
