chemical modifications of histones and DNA methylation.
Yes, physisorption is generally considered a reversible process because it involves weak van der Waals forces or electrostatic interactions between the adsorbate molecules and the adsorbent surface. This means that the adsorbate molecules can easily desorb from the surface under suitable conditions, making physisorption reversible.
Adding lemon to water is considered a reversible change because the lemon can be easily separated from the water by filtration or evaporation, leaving behind the original components of water and lemon. The lemon juice can be extracted again from the lemon by squeezing it, showing that the change is reversible.
No, digesting a banana is not a reversible change. Once the banana is broken down and its nutrients are absorbed by the body, it cannot be easily reconstituted back into its original form.
Not all physical changes are reversible. Some physical changes, such as breaking a glass or cutting a piece of paper, are irreversible because they result in a permanent change to the material's structure. Reversible changes, like melting ice or boiling water, are changes that can be easily reversed by altering the conditions.
Reversible sols are colloidal systems that can easily change their state between sol (dispersed phase in a continuous medium) and gel (semisolid) when subjected to external forces like temperature or pH changes. These systems are commonly used in industries for their ability to undergo reversible transformations.
Yes, physisorption is generally considered a reversible process because it involves weak van der Waals forces or electrostatic interactions between the adsorbate molecules and the adsorbent surface. This means that the adsorbate molecules can easily desorb from the surface under suitable conditions, making physisorption reversible.
Yes, mixing gases is a reversible change because it can be easily undone by separating the gases through processes like filtration or distillation. The individual gases retain their properties and do not chemically combine when mixed, allowing them to be separated efficiently.
chemical change is easily reversible whilst physical is not reversible
Adding lemon to water is considered a reversible change because the lemon can be easily separated from the water by filtration or evaporation, leaving behind the original components of water and lemon. The lemon juice can be extracted again from the lemon by squeezing it, showing that the change is reversible.
No, burning wax is an irreversible change. When wax is burned, it undergoes a chemical reaction that changes it into different substances (carbon dioxide, water vapor, and heat) that cannot be easily reversed.
No, digesting a banana is not a reversible change. Once the banana is broken down and its nutrients are absorbed by the body, it cannot be easily reconstituted back into its original form.

Both processes are reversible. Dissolving a substance involves the solute breaking apart into ions or molecules in the solvent, which can easily reform by removing the solvent. Similarly, acid-base reactions can go in both directions depending on the concentration of reactants and products.
The ability to rust is a chemical property because it involves a reaction between iron and oxygen to form iron oxide. This process is not easily reversible and involves a change in the chemical composition of the metal.
Ill effects when encountered much more easily reversible in humans.
No, not all chemical reactions are reversible. Some reactions are irreversible, meaning they cannot easily be reversed to reform the original reactants.
No, breaking glass is considered to be an irreversible change because the glass is physically broken into smaller pieces, which cannot be easily reassembled to its original form.
