The kinetic model theory states that the particles of gases behave as perfectly elastic spheres, exhibiting elastic collisions, where kinetic energy is conserved, whenever they hit something.
ANSWER:
B. Electrons have transferred from one atom to another.
EXPLANATION:
An oxidation-reduction (redox) reaction is a reaction which involves the change in oxidation number of the atoms involved. Since the oxidation number changes, this means that one atom has to lose electrons and another has to accept electrons. The reactant that loses electrons is called REDUCING AGENT while the reactant that gains electrons is called OXIDIZING AGENT.
For example, in a reaction between iron and oxygen as follows:
4Fe+ 3O2→2Fe2O3
Iron is reduced from +2 to 0 because it accepts electrons from oxygen while oxygen is oxidized from -2 to 0 because it transfers electrons to iron.
Hence, a redox reaction can be identified by the transfer of electrons from one atom to another.

The answer is A.)The final pressure of a gas is directly proportional to volume and temperature change.
Carbon dioxide and Water are the products of cellular respiration.
The catalytic converter of a secondary air injection system converts the hydrocarbons and carbon monoxide to carbon dioxide (CO2) and water (H2O). It is a fundamental part of a vehicle.
<h3>Catalytic converter and air injection systems</h3>
A catalytic converter refers to the device observed in a car and/or vehicle, which is used to remove different contaminant gases.
In general, the catalytic converter is placed close to the car engine and reduces the release of hydrocarbons.
In general, the air injection system is connected to the catalytic converter in order to provide useful oxygen required for oxidation reactions.
