Explanation

In paper chromatography, the stationary phase is the paper, which is made of cellulose fibers.

It holds the sample in place while the mobile phase (solvent) moves through it.

Explanation

In a bomb calorimeter, reactions are carried out at constant volume.

This is because the calorimeter is designed to keep the volume constant during the reaction.

Any heat released or absorbed during the reaction causes a temperature change, which is measured to determine the heat of the reaction.

The constant volume ensures that the heat measured is solely due to the chemical reaction taking place

Without any external influences like changes in pressure or volume.

Explanation

The reaction at the anode is called oxidation

In electrochemical cells, the anode is where oxidation occurs, meaning the substance loses electrons.

This contrasts with the cathode, where reduction (gain of electrons) takes place. 

Explanation

Mesh topology is a type of networking where all nodes cooperate to distribute data amongst each other.

Explanation

Explanation

In chromatographic analysis, the principle used is adsorption, where the components of a mixture interact with the stationary phase and are separated based on their differing affinities for the stationary phase.

Explanation

Diamond is anisotropic because its properties vary depending on the direction in which they are measured.

This is due to its crystalline structure, where the carbon atoms are arranged in a specific lattice.

The bonds between the carbon atoms are strong and are oriented along specific crystal axes.

As a result, diamond exhibits different mechanical strengths, refractive indices,

And other properties depending on the orientation of the crystal axes relative to the applied force or measurement. 

Explanation

• NaCl is also known as Sodium Chloride, or common table salt.
• It is a classic example of an ionic compound, where sodium (Na) loses an electron to become a positively charged ion (cation), and chlorine (Cl) gains an electron to become a negatively charged ion (anion).

Explanation

To find the resultant of two forces acting at right angles, use the Pythagorean theorem:

Resultant = √(3² + 4²) = √(9 + 16) = √25 = 5N
