Liquid octane (C8H18) is burned in the constant pressure, adiabatic combustor of an aircraft engine with 40% excess air. The air enters the combustor at 600 kPa and 307C, and the fuel is injected into the combustor at 25C. Estimate the temperature at which the products of combustion leave the combustor.

Ithink the answer is c i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you

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.
