Question

When the equation for the complete combustion of two mol of propyne, C3H4, is
balanced what is the sum of all the coefficients?
2C3H4(g) + __ O2(g) → __ CO2(g) + __ H2O(l)

Answer 1

the balance equation is as follows

2C3H4+5O2 - heat->6CO2 + 4H2O

it is an organic compounds contain alkyne functional group which react with air in presence of heat produce Co2 and water .
