O2 is paramagnetic due to the presence of two unpaired electrons in its molecular orbitals.

O2 has two unpaired electrons in its π* orbitals, making it paramagnetic.

O2 is paramagnetic due to the presence of two unpaired electrons in its molecular orbitals.

N2 has a triple bond, with a bond order of 3 according to molecular orbital theory.

O2 is paramagnetic due to the presence of two unpaired electrons in its molecular orbitals.

The 3s orbital has the highest principal quantum number (n=3), indicating it has the highest energy.

Binary fission is a form of asexual reproduction commonly seen in unicellular organisms like Amoeba.

Frogs exhibit external fertilization where eggs and sperm are released into the water.

Frogs typically exhibit external fertilization, where eggs and sperm are released into the water.

Radiation is the process of heat transfer that occurs without any medium.

In an isothermal process, the internal energy of an ideal gas remains constant.

In adiabatic compression, the temperature of a gas increases due to work done on it.

During a phase change, the temperature of a substance remains constant despite heat being added or removed.

In an isothermal process, the temperature of the system remains constant.

Adsorption is widely used in water purification processes to remove impurities.

In an isobaric process, the enthalpy change (ΔH) is equal to the heat absorbed or released at constant pressure.

In an isobaric process, the enthalpy change is equal to the heat absorbed by the system at constant pressure.

The combustion of gasoline releases a large amount of energy, resulting in a large enthalpy change.

The reaction N2(g) + 3H2(g) → 2NH3(g) results in a decrease in the number of gas molecules, leading to a negative change in entropy.

A liquid with high molecular weight and strong intermolecular forces will have a higher boiling point.

A liquid typically exhibits the highest density at room temperature, as it is not at the extremes of phase change.

A material exhibits elastic behavior when it returns to its original shape after the load is removed.

Plastic deformation occurs when the stress exceeds the yield point of the material.

A satellite experiences weightlessness when it is in free fall, as both the satellite and its occupants are accelerating towards the Earth at the same rate.

Conduction occurs when heat is transferred through direct contact, such as heating water in a pot.

Elastic deformation occurs when the rubber band is stretched and returns to its original shape.

Light becomes polarized by reflection when it reflects off a smooth surface at Brewster's angle.

Light becomes polarized when it reflects off a non-metallic surface, as the reflected light tends to align in a particular direction.

Viscosity generally increases when a fluid is cooled.

Light is most likely to be polarized when it reflects off a smooth surface, such as water or glass.
