How much oxygen is needed for the complete combustion of 10 l of acetylene?
Acetylene combustion equation
2С2Н2 + 5О2 = 4СО2 + 2Н2О
The stoichiometric coefficients in the equations of chemical reactions for molecules of gaseous substances show in which volumetric ratios gaseous substances react or are obtained.
V (C2H2): V (O2) = 2: 5
10: V (O2) = 2: 5
V (O2) = 5 * 10/2 = 25 L
