State one advantage and one disadvantage of using incineration for the disposal of polymers, other than the effect on climate.
Butane is used as a fuel.
The equation for the complete combustion of butane is shown.
2C4H10(g) + 13O2(g) → 8CO2(g) + 10H2O(l)
35.0 cm3 butane is completely burned in 300 cm3 oxygen.
Calculate the final total volume of gas in cm3.
All volumes are measured at the same temperature and pressure.
