Reaction to Reactions

Why should anyone be aware of chemical reactions? Chemical reactions are apart of everyday life. There are chemical reactions happening every where around us. Chemical reactions show us how molecules interact and how things work. There are reactions going on in photography, fireworks, and even when a person is breathing.

Another reaction happening in everyday life is when someone starts their car. Inside the car, the battery produces electrical charges through a chemical reaction. The battery has plates of lead and plates of lead oxide, which are fixed into a solution of water and sulfuric acid. The acid responds to the lead plates and changes the lead oxide into lead sulfate. The chemicals then produce electricity to transfer through wires in order to turn on lights and start the ignition. During recharge of the battery, the reaction reverses in direction. The recharge changes lead sulfate back to lead and lead oxide. The chemical reactions continue to happen when the car is recharged and discharged. The chemical equation for this reaction is, 
PbO2+Pb+2H2SO4 --> 2PbSO4+2H2O
