Detailed Answer

Detergents work like soaps.

It contains the polar hydrophilic and non-polar hydrophobic ends.

"The polar ends bind with the water molecule which decreases the hydrogen bonding among the water molecules".

The hydrogen bonding in water molecules causes surface tension

The intermolecular forces that are found in soaps are Vander Waals attraction, hydrogen bonds along ion-dipole interactions

Explanation

As carboxylic acids get larger (i.e., as their molecular mass increases),

They tend to have more nonpolar hydrocarbon-like portions in their structure, which can interact favorably with the hydrophobic tails of water molecules.

This increased interaction with water molecules leads to greater solubility in water.

Explanation

Hint: Canal rays also known as anode rays

Anode rays lead to mechanical motion

Kinetic energy is found in them as they produce heat

e/m ratio varies and is not constant and is dependent on the gas type used

Explanation

The electrolysis of NaCl solution gives H2 (g) at cathode and Cl2 (g) at anode.

Explanation

Propane-1,2,3-triol. Other names. Glycerin. Glycerine.

Explanation

Since the reaction order is second, the formula for t1/2=k−1[A]−10.

This means that the half-life of the reaction is 0.0259 seconds

while

For a first-order reaction, t1/2 is independent of the initial concentration of reactants.

***

The rate constant of a zero-order reaction is equal to the rate of reaction.

R: t1/2 for zero order reaction is directly proportional to the initial concentration

***

A third-order reaction is a reaction in which the rate is directly proportional to the concentration of three reacting molecules.

Explanation

Ethane dehydrogenation (EDH) is endothermic, and the thermodynamic equilibrium limits its conversion.

reason:

Because the EDH reaction is endothermic,

the reaction is favored at high temperatures for obtaining high ethane conversion, high activity, and high ethylene selectivity

Explanation

electrons have opposite spins when they are in the same orbital the condition reduces friction

Electrons are charged species that revolve around the nucleus and spin on their axis.

.Two electrons present in the same orbital have opposite spins (i.e. clockwise and anticlockwise) to cancel out the magnetic field generated by the other electron.

Explanation

Phenols are highly reactive toward electrophilic aromatic substitution

because the nonbonding electrons on oxygen stabilize the intermediate cation.

the correct order of reactivity towards electrophilic substitution is Phenol > benzene > chlorobenzene > benzoic acid.
