Explanation

In solids, particles mainly exhibit vibrational motion about their fixed positions.

They have limited translational and rotational motion compared to liquids and gases.

Explanation

Homogeneous liquid equilibria can be affected by temperature changes,

It as the temperature can influence the equilibrium position.

Pressure changes may also affect equilibria but to a lesser extent than temperature changes.

Explanation

The order of a reaction can be fractional, whereas molecularity (the number of molecules involved in the reaction)

It is always a whole number and cannot be fractional

Explanation

Be(OH)₂ is an amphoteric hydroxide, meaning it can act as both an acid and a base.

Mg(OH)₂ and Ca(OH)₂ are basic hydroxides.

Explanation

Polarization is a property of transverse waves, where the direction of vibration can be oriented in various directions.

Ultrasonic waves are longitudinal waves and cannot be polarized.

Explanation

The vector product (cross product) of two vectors gives a vector that is perpendicular to both original vectors.

Angular momentum is a vector product of position and linear momentum vectors.

Explanation

PbCl₂ (lead(II) chloride) is ionic.

Lead(II) chloride forms an ionic lattice structure with chloride ions,

while PbCl₄ is a covalent complex.

Explanation

Cilia and flagella have a characteristic "9+2" arrangement of microtubules: nine outer pairs and two central single tubules.

Explanation

Ethics is primarily concerned with questions of morality, which involves principles of right and wrong behavior.

Explanation

Honesty and integrity are fundamental components of ethical behavior, reflecting adherence to moral principles and truthfulness.
