The ground.
Practically all cars uses the chassis as return to the battery. It makes sense it eliminates wiring and at the same time it is more reliable as connection as opposed to have a return wire for every sensor lights whatever
It doesn't. A return path is needed. In a car, for example the chassis may provide return.
reduces the amount of wires needed.
'Ground' is an electrical term indicating the return path completing a circuit . ~ See related link below . The negative terminal of a car battery is connected to the chassis of the car. This defines the reference point for measuring voltages in the car. It is possible for the body of the car to be connected to the ground, such as when the car is put on a metal jack. This has no electrical effect, so the body of the car is pretty much equivalent to ground.
sulphuric
sulphuric acid
The cells in the battery are in a liquid (sulfuric acid).

You do not recharge your car battery with another car, when you connect the batteries together to get your car started, it is called jumping it, and only partially gets the battery working again. It should not be attempted if you do not know what you are doing because it can be dangerous.
did you charge the battery? check to make sure that you are not leaving a door open or a light on. If the battery is defective return it. You may need to take your car to the shop
It is called a 58 group size battery, this is a reliable answer for the fact that I own one and I work at a car battery factory.
Older cars used to use the chassis as the return path for many electrical circuits, especially the lights. However over time, corrosion at joints would reduce current flow causing lights to dim. A better way is to add a return wire back to the battery ground point to avoid this problem.
