Are you going electric ?
If you're starting out on an A level chemistry course take a little time to revise the bits of chemistry below.
You will have performed calculations involving mass changes and you will have studied combustion reactions. In the video I've done a rough calculation to see how much we think we might have reduced our annual carbon dioxide production by switching from an old car running on diesel fuel to a new petrol/electric hybrid car.
HOW DO HYBRIDS HELP?
Simple really - they burn less fuel so they produce less Carbon Dioxide...
But is that all there is to it?
Watch the video, follow the equations and calculations. They should make sense to you - but if not, ask for some help.
