Car batteries are usually 12-volt. Research car batteries and describe how such a high voltage is achieved.

When car lights are let on for a long time, this can cause a 鈥渄ead鈥� battery, which will require a jump-start from another car battery. In chemical terms, what does it mean to have a 鈥渄ead鈥� car battery? What does 鈥渏ump- starting鈥� a car battery mean in terms of the overall redox reaction? Research and report on your findings.
