Many vehicles now use biodiesel instead of standard petroleum diesel.
Suggest two reasons why biodiesel is more sustainable than petroleum diesel.
Like methane, other hydrocarbons can burn to form both carbon monoxide and carbon dioxide.
Explain the process by which carbon monoxide is produced when a hydrocarbon is burned.
Balance the equation for the incomplete combustion of butane to produce carbon monoxide:
‾C4H10(g)+‾O2(g)→‾CO(g)+‾H2O(l)\underline{\quad}\text{C}_4\text{H}_{10}\text{(g)} + \underline{\quad}\text{O}_2\text{(g)} \rightarrow \underline{\quad}\text{CO(g)} + \underline{\quad}\text{H}_2\text{O(l)}C4H10(g)+O2(g)→CO(g)+H2O(l)
Ethane burns to form carbon dioxide and water. The equation for the reaction is:
2C2H6(g)+7O2(g)→4CO2(g)+6H2O(l)2\text{C}_2\text{H}_6\text{(g)} + 7\text{O}_2\text{(g)} \rightarrow 4\text{CO}_2\text{(g)} + 6\text{H}_2\text{O(l)}2C2H6(g)+7O2(g)→4CO2(g)+6H2O(l)
4.80 dm34.80\text{ dm}^34.80 dm3 of carbon dioxide is produced when a sample of ethane is burned in 9.50 dm39.50\text{ dm}^39.50 dm3 of oxygen.
Calculate the volume of unreacted oxygen.
Give your answer in cm3\text{cm}^3cm3.
