Is the combustion of hexane complete?
Hexane is oxidised by oxygen to form carbon dioxide and water provided that the reaction is complete. Hexane is oxidised by oxygen to form carbon dioxide and water provided that the reaction is complete.
What is chemical equation of hexane?
C₆H₁₄Hexane / Formula
What reaction is a combustion reaction?
Combustion is a high-temperature exothermic (heat releasing) redox (oxygen adding) chemical reaction between a fuel and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

How do you calculate the enthalpy change of combustion of hexane?
1.15g of hexane = 0.013mol of hexane. 3) Find enthalpy change of reaction. Combustion of 1mol of hexane produces (by my calculations) -4194 kJ/mol. Therefore, 0.013mol will produce (0.013/-4194) -3.1×10-6 kJ/mol.
What is the general combustion of alkane?
All alkanes react with oxygen in a combustion reaction, although they become increasingly difficult to ignite as the number of carbon atoms increases. The general equation for complete combustion is: CnH2n+2 + ( 32n + 12) O2 → (n + 1) H2O + n CO.

How do you calculate the enthalpy of formation of hexane?
Calculate the standard enthalpy of formation of hexane using the enthalpies of combustion (in kJ/mol) given just below….Solution using enthalpy of combustions:
| C6H14(ℓ) + 19⁄2O2(g) —> 6CO2(g) + 7H2O(ℓ) | ΔH o = +4163.0 kJ |
|---|---|
| 7H2(g) + 7⁄2O2(g) —> 7H2O(ℓ) | ΔH o = −2000.6 kJ |
