Explanation

The substance with the most moles is 3.8 g of H2O (0.211 moles).

Therefore, it has the largest number of molecules. 

Explanation

 In cyclic photophosphorylation, electrons from the primary acceptor of Photosystem I (PSI) return to the cytochrome complex, specifically the cytochrome b6f complex, via ferredoxin (Fd)

.This process also involves plastoquinone (PQ) and plastocyanin (Pc) before the electrons return to PSI. 

Explanation

Glucose molecules contain multiple hydroxyl groups (-OH) which can form hydrogen bonds with water molecules, allowing them to readily dissolve in water. 

Explanation

Cotton is a natural fiber that contains a very high percentage of cellulose, typically around 95%.

Cellulose is a polysaccharide (a long chain of glucose molecules) that provides strength, structure, and durability to plant cell walls.

Cotton is one of the purest forms of cellulose, making it a valuable resource for textile production.

Explanation

A Lewis base is a substance that donates a pair of electrons to form a coordinate covalent bond.

This means that a Lewis base is an electron pair donor.

Explanation

One Faraday (F) is equal to 96,500 Coulombs (C).

The Faraday is a unit of electric charge.

It represents the amount of charge required to deposit one mole of electrons (6.022 x 10^23 electrons) at an electrode.

Explanation

• Hydrogen (H2) is the lightest molecule, with a molecular weight of 2.016 g/mol.
• According to Graham's Law of Diffusion, the rate of diffusion of a gas is inversely proportional to the square root of its molecular weight.
• Therefore, hydrogen diffuses the fastest.

Explanation

• De Broglie extended the wave-particle duality to electrons in 1923.
• He proposed that particles such as electrons exhibit wave-like properties.
• A hypothesis that was later confirmed experimentally and became a fundamental concept in quantum mechanics.

Explanation

 Sir William Ramsay, a Scottish chemist, is credited with the discovery of the noble gases.

He first discovered argon and later found neon, krypton, and xenon. 

Explanation

 Chromatography involves the distribution of mixture components between a mobile phase and a stationary phase.

The mobile phase is a fluid stream (liquid or gas) that carries the components of the mixture

While the stationary phase is a fixed material that interacts with these components

Slowing their movement and leading to separation
