Question

The octane rating of gasoline is a relationship of the burning efficiency of the given gasoline mixture to the burning efficiency of octane (C8H18). (Figure 1) Like most hydrocarbons, octane reacts with oxygen gas to produce carbon dioxide and water. The unbalanced equation for this reaction is

C8H18(g)+O2(g)CO2(g)+H2O(g)

Part A

Determine the balanced chemical equation for this reaction.

C8H18(g)+O2(g)CO2(g)+H2O(g)

Enter the coefficients for each compound in order, separated by commas. For example,1,2,3,4 would indicate one mole of C8H18, two moles of O2, three moles of CO2, and four moles of H2O.

Explanation / Answer

Balanced chemical reaction :-

2C8H18(g) + 25O2 -------> 16CO2(g) + 18H2O(g)

Thus, the coefficients in the required order are:-

2,25,16,18
