IB Chemistry SL 1.3.1 Combustion reactions
Balance complete combustion equations for fuels, then use mole ratios and Mr values to find oxygen demand, coefficients or energy released per amount burned.
How this is tested
- balance complete combustion equations for methane, ethanol and propan-1-ol using smallest whole-number coefficients
- calculate moles of O2 needed from a fuel mass and Mr, such as 11.5 g of propane
- determine coefficient totals or energy released from ΔHc°, such as for propan-1-ol or fructose respiration
