Energy is absorbed from the outer source or surrounding for the reaction to take place is known as endothermic reaction. Join I u Choice. The endothermic reaction is (iv) decomposition of calcium carbonate to form quick-lime and carbon dioxide. Answer:iv) Decomposition of calcium carbonate to form quick lime and carbon dioxide. Chemical reaction initiated by … Which of the following reactions is an endothermic reaction? The decomposition is due to sunlight or light bulb. Other articles where Silver bromide is discussed: bromine: Production and use: Silver bromide (AgBr), an important component of photographic film, is, like silver chloride and iodide, light sensitive. Heat absorbed in this reaction resulting in the formation of calcium oxide or quick-lime and carbon dioxide. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. Nor do they change from one element to atoms of another element. Silver bromide is a light-sensitive compound that is it gets decomposed when exposed to light. The calcium carbonate can be heated so as to undergo thermal decomposition and form products like calcium oxide and water. Silver bromide (AgBr), a soft, pale-yellow, water-insoluble salt well known (along with other silver halides) for its unusual sensitivity to light.This property has allowed silver halides to become the basis of modern photographic materials. 2AgBr (s) -------------------> 2Ag (s) + Br2 (g). • Traces of potassium bromate (KBrO3) are added to wheat flour to improve baking. White silver chloride turns grey in sunlight. Answer: The endothermic reaction is (iv) decomposition of calcium carbonate to form quick-lime and carbon dioxide.. Most decomposition reactions require energy either in the … Your IP: 5.135.139.84 The reaction is given as follows: 2AgBr(s)→ 2Ag(s) + Br2(g) In fact, during chemical reactions, bonds between atoms are broken and re-made to give rise to new substances. Let’s understand how this happens in different types of reactions. Why photosynthesis is called an endothermic reaction? Silver Bromide is exposed to light, it decomposes to silver metal and bromine vapours. Why are decomposition reactions mostly endothermic in nature? This reaction takes place at a temperature of 700°C or at room temperature. You may need to download version 2.0 now from the Chrome Web Store. In this reaction, calcium carbonate decompose in the presence of energy formed by the heat (thermal decomposition). If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. For example, decomposition of calcium carbonate is not a redox reaction. During a chemical reaction, atoms do not disappear from the mixture and appear elsewhere. Decomposition of hydrogen peroxide: In the presence of light, hydrogen peroxide decomposes into water and oxygen . On analysis, it is found that the sunlight has caused decomposition of silver chloride into silver and chlorine. • All the decomposition reactions are not redox reactions. Explanation: In this reaction, calcium carbonate decompose in the presence of energy formed by the heat (thermal decomposition).Heat absorbed in this reaction resulting in the formation of calcium oxide or quick-lime and carbon dioxide. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Performance & security by Cloudflare, Please complete the security check to access. The decomposition of silver(II) bromide to produce silver(I) and bromine. Cloudflare Ray ID: 5f87fce38839d8f9 Silver chloride is decomposed by sunlight into silver and chlorine. This decomposition occurs when light is supplied to reactants in the form of energy. Silver bromide also decomposes in the same way. State the differences between exothermic and endothermic reactions. The strongly heated calcium carbonate absorbs heat from the reaction to form a solid (quick lime) and gas (carbon dioxide). Other bromine compounds of significance include hydrogen bromide (HBr), a colourless gas used as a… Calcium oxide dissolved in water forms lime water which is nothing but calcium hydroxide.

The above reaction is used in black and white photography. AgBr is widely used in photographic films and is believed by some to have been used for making the Shroud of Turin. Another way to prevent getting this page in the future is to use Privacy Pass. So when silver bromide is exposed to sunlight, it gets decomposed to give silver metal and bromine gas is liberated. This site is using cookies under cookie policy. The endothermic reaction is the reaction in which the heat is absorbed in the reaction to form the products. In this reactions, pale yellow colour of silver bromide changes to greyish white due to formation of silver metal.
