Is dissolution of common salt is chemical or physical change?
It is a physical process; on the other hand dissociation in water is a chemical process.
Does dissolution and crystallization produce heat?
Dissolution typically absorbs heat from the surroundings as the solute particles separate and mix with the solvent, causing a decrease in temperature. Crystallization on the other hand releases heat as the solute particles come together to form a solid crystal structure, leading to an increase in temperature.
What happen when heat from the iron reaches the hand the process is known as?
When heat from the iron reaches the hand, the process is known as conduction. This occurs as thermal energy transfers from the hotter object (the iron) to the cooler object (the hand) through direct contact. The heat causes the temperature of the hand to increase, which can lead to pain or burns if the contact is prolonged.
Which pill design tablet caplet capsule will dissolve faster?
Generally, capsules tend to dissolve faster than tablets or caplets. This is because capsules are typically made from gelatin or a similar material that dissolves quickly in the stomach. Tablets and caplets, on the other hand, may have coatings or binders that can delay dissolution. However, specific formulations and individual factors like stomach pH can also influence dissolution rates.
What is the difference between physical and chemical dissolution?
Physical dissolution is purely mechanical; an example would be shaking a bottle of Italian salad dressing, the different ingredients mix but don't form a new substance. Chemical dissolution produces new substances; for example, mixing NaOH with HCl forms water and table salt, two chemicals different from what you had to begin with. Also, dissolving table salt in water is a chemical change, though it may not seem like it.When adding water:NaCl (s) => Na+ (aq) + Cl- (aq)This is a very soluble ionic compound and it changes from a neutral compound to ions, a chemical change.The dissolution of non-ionic compounds, such as sugar, is not a chemical reaction because sugar doesn't separate to ions in solution. i.e., this is a physical dissolution.When adding water:C6H12O6 (s) => C6H12O6 (aq)The dissolution of weak electrolytes is somewhat more complicated. Let's consider acetic acid (vinegar).When adding water:CH3COOH (s) => CH3COOH (aq)Although we write the dissolution for a weak acid or weak base this way, it differs from the sugar example because we know that, actually, some of the molecules go to CH3COO- and H3O+. We don't write this, though, because although some molecules have undergone a chemical reaction, that population is a minority.
Is dissolution of common salt is chemical or physical change?

Why to use check?
You use cheques as a a substitute for cash when you don't have enough cash in hand. You can use cheques at banks, shops etc. Cheques are negotiable instruments that can be treated at par with cash.
What is difference between dissolution and solubility of a product?
Type your answer here... Dissolution is a rate process that is it is dependant on time. It is dynamic process. While solubility is a static property, does not dependant on time. also solubility is a inherent property.
What is the difference cash at bank and hand in cash and overdraft?
The difference between Cash on Hand from Cash in Bank is that the cash is on our hand while the other one is that cash is not in our hand but in the bank. Serioulsy, I really dont know. Thank you very much!
What is meant by cash out refinancing?
Cash Out Refinancing refers to a process that banks can offer that will cover the equity in the home above all other fees hopefully leaving the individual with extra cash in hand.
What is the difference between dissolution and disintegration in capsule and tablet?
Dissolution is the process by which a drug substance dissolves in a liquid medium, such as gastric fluid, to become available for absorption. Disintegration, on the other hand, refers to the breaking apart of the tablet or capsule into smaller particles. Disintegration occurs first to increase the surface area for dissolution to happen efficiently.
Is cash on hand an asset?

What is the cash management of a commercial bank?
Money is an account balance. Banks do not maintain cash on hand equal to the amount of money deposited. Rather, they keep about 10% of deposited funds in cash. The amount required varies from day to day and week to week. Cash management is keeping enough cash on hand to handle the bank's cash business plus the cash reserve dictated by the bank's policy. Cash on hand plus cash deposited minus cash paid out equals net cash on hand. To ensure that the net cash on hand meets the bank's needs, the cash manager must estimate with fair accuracy the amount of cash to be deposited as well as the future cash demand. Cash is ordered from the federal reserve and excess cash is returned there.
