Question 57

The equation shows the complete combustion of hexane gas:

C6H14(g)+9.5O2(g)→6CO2(g)+7H2O(g) \text{C}_{6}\text{H}_{14}(\text{g}) + 9.5\text{O}_{2}(\text{g}) \rightarrow 6\text{CO}_{2}(\text{g}) + 7\text{H}_{2}\text{O}(\text{g}) C6​H14​(g)+9.5O2​(g)→6CO2​(g)+7H2​O(g)

What happens to the hexane in this reaction?

A

hexane is neutralised

B

hexane is reduced

C

hexane is oxidised

D
