What has the strongest intermolecular forces of attraction?
Answers
The strength of intermolecular forces of attraction varies depending on the type of molecules involved. In general, the order of increasing strength of intermolecular forces is as follows:
1. **London Dispersion Forces (Van der Waals Forces):** These are the weakest intermolecular forces and occur in all molecules. They are caused by temporary fluctuations in electron distribution, leading to temporary partial charges. London dispersion forces are stronger in larger and more polarizable molecules.
2. **Dipole-Dipole Forces:** These forces occur between polar molecules with permanent dipoles. They are stronger than London dispersion forces and result from the attraction between the positive end of one molecule and the negative end of another.
3. **Hydrogen Bonding:** This is the strongest type of intermolecular force. It occurs when hydrogen is bonded to a highly electronegative atom (such as nitrogen, oxygen, or fluorine) and is attracted to another electronegative atom in a different molecule. Hydrogen bonds are responsible for the unique properties of substances like water and ammonia.
So, hydrogen bonding generally represents the strongest intermolecular force of attraction among these three types. However, it's important to note that the actual strength of these forces can also depend on factors such as molecular size, shape, and temperature.

The correct answer fro above statement is:
False
Explanation:
Some elements in the atmosphere start the body and are consistent when they are dropped. Others are diminishing. Degradation stocks may be more lethal or less virulent than the first chemical. Other chemicals are deposited momentarily in the organs and are discharged shortly after. After a while, most chemicals and degradation stocks are ordered of as body waste, in the stool, urine, sweat and breathed air.

Statement-1 is the correct answer that is Endothermic reactions absorb heat energy while exothermic reactions release heat energy.
How can we distinguish between exothermic and endothermic processes?
Chemical reactions that release energy are referred to as exothermic. More energy is produced than is needed to break the bonds between the reactants when bonds are formed in the byproducts of exothermic processes.
Chemical processes that either use or absorb energy are referred to as endothermic. In endothermic reactions, more energy is absorbed when bonds in the reactants are broken than is released when new bonds are formed in the products. Since an isothermic chemical reaction uses exactly as much energy as it produces, there is no net energy change.
Therefore, the first statement is the right response.

Answer: The alpha particle is released after alpha radiation.
Explanation:
Alpha decay is defined as the decay process in which a heavier nucleus decays into a lighter nuclei. This decay process releases alpha particle which is also known as helium nucleus.
The general alpha decay reaction is given as:
The particle released will carry a mass of 4 units and carries a charge of +2 units.
Hence, the alpha particle is released after alpha radiation.

Answer: b. there is no net change in the amount of substrates or products.
Explanation:
The reactions which do not go on completion and in which the reactant forms product and the products goes back to the reactants simultaneously are known as equilibrium reactions.
Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.
For a chemical equilibrium reaction, equilibrium state is achieved when the rate of forward reaction becomes equals to rate of the backward reaction.

Explanation:
Reference Table S lists the electronegativity of each element. The greater the difference in electronegativity, the more polar the bond. The electronegativity of H is 2.2 and the electronegativity of Cl is 3.2; the difference is the greatest of the choices listed.
