Balance the following equation and then answer the following question. How many molecules of carbon dioxide are produced when the following reaction occurs? C2H50H (aq) +_ 02 (g) →_ CO2 (g) + _ H20 (g) 3. 4.

The answer is solid copper 

H tricky one let me think and get back to u

Anyone know the answer?

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.
