Why does quicklime heat up when water is added?

Why does lime produce high temperatures when it hits water, and what is the principle? Today is a long time to see.

Quicklime: cao. Quicklime reacts chemically with water and is immediately heated to temperatures of over 300 °C. CA + H2O ==== Ca(OH)2 This reaction is exothermic!

Quicklime, the main component is calcium oxide, usually prepared by calcination of natural rock with the main component of calcium carbonate at high temperature, which can be decomposed to generate carbon dioxide and calcium oxide (chemical formula: CAO, that is, quicklime, also known as marble).

All natural rocks with calcium carbonate as the main component, such as limestone, chalk, dolomitic limestone, etc., can be used to produce lime. Quicklime reacts with water to release heat and produce chemically stable hydrated lime.

quicklime process-exclusive chemical process. It is the water molecules of solute molecules or ions that are formed in solution that release energy in the form of water molecules or ions hydration, hydration molecules, or hydration ion ion chromatography to make itself a minimum energy stable and hence the procedure is an exothermic process.

When the energy absorbed by quicklime in these two processes is meaningless, the temperature of the quicklime solution does not change much, such as sodium chloride dissolved in water. When the energy released is less than the absorbed energy, the temperature of the solution, such as quicklime, concentrated sulfuric acid, etc. When absorbing energy to recombinate multiple energies, reduce the temperature of the solution, such as ammonium nitrate, etc.

The reaction is quick, the water is quicklime, the total energy of the water shock wave and the expansion reaction is higher than the total energy of the hydrated lime, hence the performance of the exothermic reaction process.

Why does lime produce high temperatures when it hits water, and what is the principle? Today is a long time to see.

The main ingredient of quicklime is CAO, which reacts with water to form calcium hydroxide, which is an exothermic reaction, so the temperature rises.

Quicklime will react with water to form calcium hydroxide, exothermic reaction, so it will heat up, as for natural, I haven't seen him catch fire in water, but white phosphorus is estimated to be able to burn ...... if it is put in hot water and then ventilated with air

Because quicklime is also calcium oxide,Calcium oxide is active. When it encounters water, it becomes mature lime, in which heat is released by the process.

The chemical composition of quicklime is calcium oxide. Calcium oxide is very active in nature, and when it encounters water, it must be "trapped" and turned into mature lime. This chemical reaction process releases heat high enough to boil the water.

Quicklime is mainly calcium oxide, which is made from natural rocks, mainly composed of calcium carbonate, and when calcined at high temperatures, it decomposes to form carbon dioxide and calcium oxide (formerly known as cao, i.e. quicklime, marble). Lime can be produced from natural rocks composed mainly of calcium carbonate, such as limestone, chalk and dolomite limestone.

Quicklime is a desiccant commonly used to remove water vapor by chemical absorption, and is also used for the dehydration of steel, pesticides, drugs, desiccant, tanning and alcohol. It is especially suitable for products such as puffed food, mushrooms, fungi, etc., as well as instrumentation, medicine, clothing, telecommunications, leather, textiles and other industrial products.

Limestone and limestone are widely used as building materials and are important raw materials in many industries. Limestone can be processed directly into stone and then fired into quicklime. Lime has quicklime and lime.

The main component of quicklime is cao, and when it contains impurities, it is usually lumpy, pure white, light gray or yellow. Quicklime becomes mature lime by absorbing water or adding water, quicklime is also known as hydrated lime, and the main component is Ca(OH). Calcined lime is mixed with lime paste, lime paste, lime mortar, etc., to be used as a coating and tile adhesive.

Soda ash is obtained by a multi-stage reaction with limestone, salt, ammonia and other raw materials (Solva method). Caustic soda (causticizing method) is prepared by reacting hydrated lime with soda ash. There are 1,286 deposits, including 257 large deposits, 481 medium-sized mines, and 486 small-scale deposits (more than 80 million tons of large-scale deposits, 100 million tons of medium-sized deposits, and 40 million tons of small-scale deposits).

less than). tonnes account for 93 of the limestone deposits of 50.4 billion tons, and marble reserves of 3.8 billion tonnes account for 7.

Because when an object has a chemical reaction with another object, the atoms of the object will be split or fused, and the original atom will be broken when splitting, which is equivalent to the original match sliding on a smooth plane, and once the smooth plane is changed, the friction will be the same. Once the uneven plane is polished flat, the properties are inactive, and the atoms of each substance are different, that is to say, the running plane of each substance is different, the rough one will be active, the smooth one will not be active, and the release of the reaction is also the key.

Because there is a certain chemical reaction, it will be accompanied by the release of heat.

Because the components of lime powder react with water, a large amount of hot gas is generated.

Because the component of lime is calcium oxide, calcium oxide reacts with water to release heat.

Because lime water will undergo some chemical reactions when it encounters water, it will heat up.

Calcium oxide reacts with water to produce mature lime calcium hydroxide is an exothermic reaction, so the result you described appears.

Why does lime produce high temperatures when it hits water, and what is the principle? Today is a long time to see.

It's just a simple chemical reaction.

LZ and my name are like, my name is Wu Mengzhou. When quicklime Cao reacts with water to produce mature lime Ca(OH)2, it will release a lot of heat. Boiled eggs, like the second floor said, depends on how you get it. Put an egg in a pile of lime and water it. Khan

If you want to boil eggs, it depends on how you make lime, if you want to boil, you have to water the lime first, and then you can put the eggs after 1 or 2 minutes, that way, if you put the eggs in the lime first, you are watering, the lime will break the eggs.

For various reasons, it is a chemical reaction that produces heat.

Quicklime becomes mature lime when exposed to water, and at the same time emits a large amount of heat.

Quicklime is CAO, that is, calcium oxide, which is actually not the lime we are talking about.

The lime we usually refer to as Ca(OH)2 reacts as follows when it comes into contact with water

CaO+H2O=Ca(OH)2+Heat.

It is a chemical phenomenon in which quicklime is exothermic when exposed to water.

The chemical composition of quicklime is CaO, which reacts with water (HO) to form calcium hydroxide Ca(OH) and release heat, it's as simple as that. The chemical equation is as follows:

cao ＋h₂o ＝ ca（oh）₂

Very simply, CAO is calcium oxide, commonly known as quicklime, and H2O, that is, water, reacts to form calcium hydroxide, releasing a lot of heat in the process.

Lime (calcium carbonate) and water (HO) undergo a chemical reaction to release heat.

However, if the lime is not pure lime, there are many impurities, or it has deteriorated, the heat released is less quicklime, that is: cao hydrated lime is: ca(oh)2cao+h2o=ca(oh)2+ heat.

Quicklime is soluble in water: CaO+H2O = Ca(OH)2The reaction releases heat!

Quicklime and water form calcium hydroxide, which is an exothermic reaction.

Quicklime is cao, which reacts with water.

cao+h2o=ca(oh)2

It is an exothermic process, so the water gets hot.
