When you start your car, do you think  chemistry? Probably not, but you should. The power to start your car is furnished  a lead storage battery. How does this battery work, and what does it contain? When a battery goes dead, what does that mean? If you use a friend's car to "jump start" your car, did you know that your battery could explode? How can you avoid such an unpleasant possibility? What is  the gasoline that you put  your tank, how does it furnish the energy to drive to school?
