# Problem: Consider the unbalanced equation for the combustion of hexane:C6H14(g) + O2(g) → CO2(g) + H2O(g)Determine how many moles of O2 are required to react completely with 6.1 moles C6H14.

###### FREE Expert Solution

Unbalanced reaction:

C6H14(g) + O2(g) → CO2(g) + H2O(g)

Balance C:

C6H14(g) + O2(g) → 6 CO2(g) + H2O(g)

Balance H:

C6H14(g) + O2(g) → 6 CO2(g) + 7 H2O(g)

Balance O:

C6H14(g) + 19/2 O2(g) → 6 CO2(g) + 7 H2O(g)

moles C6H14 (mole-to-mole comparison) → moles O2
