When the computer receives a rich signal (high voltage) from the O2 sensor, it leans the fuel mixture to reduce the sensor's reading. When the O2 sensor reading goes lean (low voltage), the computer reverses again making the fuel mixture go rich.
Chemistry and physics are branches of science that both study matter. The difference between the two lies in their scope and approach. Chemists and physicists are trained differently, and they have different professional roles, even when working in a team.
Quantum Chemistry. a branch of theoretical chemistry that considers problems of structure and reactivity of chemical compounds as well as problems of bonding from the point of view of the concepts and methods of quantum mechanics.n principle, quantum mechanics permits calculation of the properties of atomic and molecular systems on the basis of the Schroedinger schrÃ¶dinger, Equation pauli exclusion, principle and universal physical. constants
