?Explain what happens, on the molecular level, in the primary and secondary combustion of acetylene.
What will be an ideal response?
?In the primary reaction of acetylene (C2H2), the oxygen (O2) atoms unite with the carbon (C) atoms. This reaction liberates energy and forms carbon monoxide (CO) and free hydrogen.?In the secondary reaction, oxygen (O2) from the surrounding air unites with free hydrogen (H) to form water vapor (H2O) and liberates more heat. Also, the carbon monoxide (CO) unites with additional oxygen (O2) from the air to form carbon dioxide (CO2).
