MgCO_{3 (s)} + H₂SO_{4 (aq)} --> MgSO_{4 (aq)} + CO_{2 (g)} + H₂O _(l)

Alternative Fuels

• Ethanol and Bio Diesel

E.g. From Sugar Canes via fermentation.

Pro - Some CO2 is captured and 'reused'.

Pro - Reduces the demand for fossil fuel.

Con - More expensive than fossil fuels.

Con - Plants are fragile.

Con - Ridiculous land needed to provide the amount of fuel required.

• LPG - Liquefied Petroleum Gas

60% Propane, 40% Butane

Pro - Less CO, NO, and unburnt fuels.

Pro - Cheaper as compared with common fossil fuels.

Con - Difficult to store.

Con - Greater evaporative emissions.

• Hydrogen

Can be consumed in two ways:

1- Via burning: Like common fossil fuels, producing some NOx and water.

2- Via fuel cells: taking place in a cell rather than an engine, producing pure electricity.

Pro - Little or no pollution.

Pro - Semi infinite source of energy.

Con - Difficult to manufacture and store.

*Can be obtained from water via electrolysis.

• Nuclear Energy

Produced via the breaking down of unstable nuclei.

Pro - Long life span.

Con - Expensive and difficult to build and manufacture.
