Reaction when the anhydrous salt samples were treated with the liquid?

∙ 11y ago
Usually, when a salt anhydrate is treated with water, its crystalline structure will reappear. Many solids are crystalline when the water of hydration, or water of crystallization is present. If you vaporize this away with heat, the crystalline structure collapses and you are usually left with a powdery anhydrate. Add water and it re-crystallizes. Be careful though: adding the water back will also release the heat you put into it to remove it. So adding the water is an exothermic process.

What turns anhydrous ammonia to liquid?
Anhydrous Ammonia (aka, NH3, Refrigeration Grade) can be turned into a liquid by either intense cooling or by compressing the gas.
Can anhydrous ammonia become liquid ammonia?
Anhydrous ammonia is usually stored as a liquid by keeping it under pressure. It is more efficient to store it that way than as a gas.
What can you conclude about two liquid samples that have boiling points?
deas
Is liquid nitrogen supposed to be left on the skin after treatment?
Nitrogen must be cooled to a very low temperature to become liquid nitrogen. At room temperature, liquid nitrogen will change from the liquid phase to the gas phase. Therefore, if the skin is treated with liquid nitrogen, the liquid nitrogen will almost instantly become a gas and evaporate away from the skin. It is impossible to "leave" it on the skin, as this reaction is almost instantaneous and no liquid nitrogen is left behind.
What is the difference between anhydrous ammonia and aqua ammonia?
Anhydrous ammonia is standard, commercial grade ammonia. The term "anhydrous ammonia" emphasizes the absence of water in the material. Because ammonia boils at -33.34 °C, the liquid must be stored under high pressure or at low temperature. Aqua ammonia is another name for ammonium hydroxide, a solution of ammonia in water. This is the household ammonia offered in stores and used in some cleaning products.

A disadvantage of the ICP-OES is that it only accepts?
Liquid samples
Which of the liquid sample is most likey subtances?
Liquid samples are most likely to evaporate when temperature is increased.
What is difference between hydrogen chloride and anhydrous hydrogen chloride?
uhm i typed it in and found this:CoCl2.6H2O is the hexahydrate of anhydrous Cobalt Chloride (anhydrous meaning is without water).pretty much anhydydrous is without water that is the difference (the prefix A- is "without" or "not") and the formula one does have water.it was a question previously asked on wikianswers, so im pretty confident about it.CoCl2.6H2O is the hexahydrate of anhydrous CoCl2 (anhydrous meaning is without water).
Is a liquid endothermic or exothemic?
A liquid on its own cannot be described as either endothermic or exothermic. The terms endothermic and exothermic are the names of two opposite process reactions. An endothermic reaction absorbs heat and and exothermic reaction gives off heat. A liquid can be involved in either an endothermic reaction or in an exothermic reaction. If you are evaporating a liquid from its liquid phase to its gas phase, then the reaction is usually endothermic and vice versa, going from the gas phase to the liquid phase, the reaction is usually exothermic.
What chemical reaction is juice?
Juice is not a reaction; it is a liquid mixture.

If you have three 10g samples of water ice liquid and vapor how do the volumes of these three samples compare with one another?
The liquid water has the smallest volume. The steamy gaseous water vapor has the largest volume ... at least at atmospheric pressure ... and the volume of the ice is the intermediate one.
How would you find the density of a lump of sodium that is about 10 grams?
The volume must be determined; try the method of liquid displacement using an anhydrous mineral oil.
Can there be a solid and liquid in the product of a reaction?
Yes, a reaction can have both liquid and solid products. For example, Ba(OH) + H2SO3 ---> H2O(l) + BaSO3(S)
