Why can't you refreeze instant cold packs?
actually, you can.
What is in instant heat packs?
Instant heat packs contain a supersaturated solution of sodium acetate that heats up when the crystallization process is started by flexing a metal disc embedded in the liquid. Since the liquid is supersaturated (concentration of a solution beyond saturation point), flexing the notched ferrous metal disc makes the solution crystallize suddenly, thereby releasing the energy of the crystal lattice.
What chemicals react to make a hot pack hot?
Yes, hot packs have exothermic reactions (the contents create heat) and cold packs have endothermic reactions (they require heat to occur, therefore making the surroundings colder). In hot packs its a reaction between water and a salt solution, and in cold packs its normally water and ammonium nitrate. peeace
Who invented instant cold packs?
The first of the instant cold packs was a liquid-type invented by Albert A. Robbins and patented August 11, 1959. Robbins' "Chemical Freezing Package" involved and outer pouch containing two separate compartments for water and ammonium nitrate that would mix and freeze when the user split a perforation between the two - say by hitting or snapping the package as we would with the modern variety. Robbins' patent was assigned to Kwik-Kold of America. Parent company Cardinal Health continues to market this, and the more recently invented gel-type cold packs, to this day.
Does the bobcat live with other bobcats?
Bobcats do not go in packs, It is rare is see them go in packs. They hunt alone and do not go in packs.
Can you make meth with urea cold packs instead of ammonia nitrate?
no you cant. your thinking of the shake n bake one pot method and one has to use amonia nitrate, not urea.
Formula for ammonium nitrate?
The formula of ammonium nitrate is NH4NO3. By the way, to make ammonium nitrate, add nitric acid to ammonia. Ammonium nitrate is used commercially in instant cold packs.
Do Walgreen's cold pack contain ammoniun nitrate?
is there ammonium nitrate found in walgreens cold packs
Instant cold packs can be reused?
Instant cold packs cannot be reused once they are activated. The chemical makeup inside the package was created for one time use.
What is the chemical equation for ammonium nitrate decomposes into nitrogen and water?
When ammonium nitrate (NH4NO3) is mixed with water, the dissolution of ammonium nitrate occurs - that is, it is broken up into its ions. This is endothermic, and is the driving reaction behind instant cold packs.
Why is ammonium nitrate salt famous?
Ammonium nitrate is a very common fertilizer; also used in explosives and cold packs.
Are sodium acetate instant heat packs mixtures?
Yes, the compound in the packs is a supersaturated solution of sodium acetate.
Does ammonium nitrate absorb heat?
yes when disolved in water. It is in cold packs.
What can be mixed to produce a very cold effect that doesn't give off an unsafe gas?
Instant cold packs use water and ammonium nitrate. The ammonium nitrate is a powder found inside the cold pack, and the water is inside a plastic container inside the cold pack. When the plastic container containing the water is broken and mixed with the ammonium nitrate, the water dissolves the ammonium nitrate, which is overall an endothermic reaction, causing the cold pack to get cold.
Where can you find ammonium nirate?
inside most instant cold packs
How do cold packs work?
Instant hot and cold packs are used by athletes to quickly and conveniently treat an injury. They last for about 20 minutes. The packs take advantage of chemicals that either absorb a lot of heat or release a lot of heat when dissolved in water. When a chemical process absorbs a lot of heat it is called endothermic. When heat is released, it is called exothermic. In cold packs, ammonium nitrate is used because it absorbs a lot of heat when it dissolves in water. The water and ammonium nitrate are in separate compartments in the pack. When the cold pack is needed, the chambers are broken and the ammonium nitrate dissolves in the water, absorbing heat and making the pack as cold as 0C. In hot packs, calcium chloride or magnesium sulphate are used, along with the water. They release heat when the chambers are broken and the chemical dissolves in the water. A hot pack can reach a temperature of 90C. :)
