When 2.13 moles of C3H8 burn in excess oxygen, how many moles of CO2 will be formed assume this is complete combustion
To study the effect of a weakly acidic medium on the rate of corrosion of a metal, a chemist prepared a buffer solution by making it 0.11 M NaC2H3O2
Acetylene gas (C2H2) burns with oxygen in an oxyacetylene torch to produce carbon dioxide, water vapor, and the great heat needed for welding metals. The heat of combustion of acetylene is 1259 kJ/mol.
What is the equilibrium constant Kc for the reaction below? Assume temperature is 25oC. (Represent the reaction below as a sum of reactions and then combine the corresponding K values to obtain Kc for the reaction below.)
