H2O → H2 + O2 involves the oxidation of water to hydrogen and oxygen, making it a redox reaction.

In the reaction Fe2O3 + 3CO → 2Fe + 3CO2, iron (Fe) is reduced as it gains electrons from carbon monoxide (CO).

0.1 M glucose is a non-electrolyte and does not dissociate, thus it has the highest freezing point compared to the ionic solutions.

Carbon (C) acts as a reducing agent as it donates electrons to reduce Fe2O3 to Fe.

Carbon (C) acts as a reducing agent as it donates electrons to reduce Fe2O3 to Fe.

Carboxylic acids are more acidic than alcohols due to the resonance stabilization of their conjugate base, making the statement 'They are less acidic than alcohols' incorrect.

Not all coordination compounds are colored; the color depends on the nature of the metal and the ligands involved. Some coordination compounds can be colorless.

Thermal conductivity is a measure of a material's ability to conduct heat; it varies with material type.

Adsorption is a surface phenomenon as it occurs at the interface between phases.

Coordination compounds can exhibit optical isomerism due to the arrangement of ligands around the central metal ion.

Galvanic cells convert chemical energy into electrical energy spontaneously.

A convex lens can form both real and virtual images depending on the position of the object relative to the focal point.

The law of conservation of energy states that energy cannot be created or destroyed, but it can be transformed from one form to another.

In an adiabatic process, there is no heat exchange with the surroundings, and the temperature of the system changes due to work done on or by the system.

In an isochoric process, the volume of the system remains constant.

The complex [Fe(CN)6]3- is a low-spin complex due to the strong field nature of CN- ligands, resulting in paired electrons.

Adsorption isotherms describe the relationship between the amount of adsorbate on the adsorbent and its pressure at a constant temperature, illustrating how adsorption varies with pressure.

Gravitational fields are always attractive, pulling masses towards each other.

Reduction is defined as the gain of electrons, and it always occurs simultaneously with oxidation in redox reactions.

The Freundlich adsorption isotherm is applicable to heterogeneous surfaces and describes how adsorption varies with pressure or concentration, indicating that it is not limited to monolayer adsorption.

The Freundlich adsorption isotherm describes heterogeneous adsorption on surfaces with varying affinities, making it suitable for real-world applications.

The uncertainty principle states that position and momentum cannot be precisely known at the same time.

Thermal conductivity is a measure of a material's ability to conduct heat; it varies with material and temperature.

Solids have a definite shape due to closely packed particles that do not move freely.

Liquids have a definite volume but take the shape of their container.

Plasma has the highest kinetic energy as it consists of ionized gases with free-moving charged particles.

Gases have the least intermolecular forces, allowing particles to move freely.

Phosphorus is essential for the formation of DNA as it is part of the backbone structure.

Carbon is known for its allotropes, including diamond and graphite.

PLA (Polylactic Acid) is a commonly used polymer in 3D printing due to its ease of use and biodegradability.
