Given the equations and the values of AH' for the combustion of CH (9) and the combustion of C(graphite) represented above, which of the following additional information is needed to determine the values of AH' for the overall reaction 2 C(graphite) + 3 H2(g) → C2H6(g)?

Bthe s the

What do you need with it’s not a question your just stating what it says

The answer this would be radiative zone

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.
