Explanation

Dipole-induced dipole force is the weakest among intermolecular forces, caused when a polar molecule induces a dipole in a nonpolar molecule.

It is weaker than dipole-dipole and ion-dipole interactions.

Explanation

The science of chemical characteristics falls under the heading of analytical chemistry.

Analytical chemistry focuses on the study of the composition and structure of matter, which includes identifying and characterizing its chemical properties.

Explanation

Explanation

Relative atomic mass is measured by comparing an atom's mass to 1/12th the mass of a carbon-12 atom.

Carbon-12 is the standard reference in modern atomic mass scale.

Explanation

The comparative rates at which solutes move in paper chromatography depend on Rf values. 

Rf values (retention factors) represent the ratio of the distance traveled by a solute to the distance traveled by the solvent front on the paper.

Since different solutes have different polarities and affinities for the mobile and stationary phases, they will travel at different speeds, resulting in unique Rf values.

Therefore, the comparative movement of solutes is directly related to their Rf values. 

Explanation

A ductile material can undergo significant plastic deformation, meaning it can be stretched or bent without breaking, before fracturing.

This property is known as ductility, and it allows for large strains to occur before the material reaches its breaking point.

Common examples of ductile materials include metals such as copper, aluminum, and steel, as well as certain polymers. 

Explanation

Van der Waals forces are the weakest type of intermolecular force because they arise from temporary fluctuations in electron distribution, leading to very weak, temporary dipole-dipole interactions. 

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

To prepare 250 cm³ (or 250 mL) of a 1 M NaOH solution, you need 10 grams of NaOH.

This is because the molar mass of NaOH is 40 g/mol, and a 1 M solution contains 1 mole of solute per liter of solution.

Therefore, 250 mL (0.25 L) of a 1 M solution would require 0.25 moles of NaOH, which translates to 10 grams (0.25 moles * 40 g/mol).
