Final answer:
The correct answer is A) Reactants: Chemicals in the battery, Products: Electrical energy. Car batteries operate on the principles of galvanic cells with reactants being lead, lead oxide, and sulfuric acid, and produce electrical energy through chemical reactions.
Step-by-step explanation:
The inside of a car battery is similar to a chemical factory, engaging in a set of reactions to generate electrical energy. The reactants (inputs) of a car battery typically include lead, lead oxide, and sulfuric acid, which are contained within the battery. As the reactant materials undergo chemical reactions, electrical energy is produced as the main product (output).
The correct option for the reactants and products of the chemical reactions in a car battery is: A) Reactants: Chemicals in the battery, Products: Electrical energy. When the battery is used, it discharges, creating an electric current as the lead and lead oxide plates react with the sulfuric acid electrolyte. This results in the production of electricity, which then powers the vehicle's systems.
Car batteries are based on the principles of galvanic cells, where solids or pastes act as reactants. These batteries are ingeniously engineered to maintain a constant voltage output throughout their discharge, by using concentrated reactants that do not greatly change in concentration as energy is extracted.
