What of reaction is the reaction of quick lime with water? - Toppr Calcium oxide reacts with water to form calcium hydroxide, also called slaked lime Here are the equations for this reaction: Calcium oxide + water → calcium hydroxide CaO +H 2O → Ca(OH)2 A lot of heat is produced in the reaction, which may even cause the water to boil Hence it is a combination reaction as well as exothermic reaction
Which of the following are exothermic processes? - Toppr When water reacts with quick lime, calcium hydroxide is formed along with the release of heat Thus, it is an exothermic reaction The process of diluting a concentrated acid is a highly exothermic process
Ammonia gas can be dried over - Toppr Assertion :Hydrogen chloride gas can be dried over quick lime Reason: HCl is less reactive and it reacts with calcium oxide to form calcium oxychloride and does not absorb water in the reaction
What is the temperature required to produce quick lime? The process that is used to prepare burnt lime is known as calcination It is a process which starts with thermally decomposing the reactants at high temperatures but ensuring that the temperature is kept well below the melting point Calcium carbonate undergoes calcination at temperatures ranging between 1070 oC - 1270 o C CaCO 3 → CaO + CO 2 This reaction is reversible and exothermic in
How can quick lime be prepared from slaked lime? - Toppr Calcium oxide or Quick lime can be obtained from slaked lime by heating slaked lime to above 500o C Slaked lime them decomposes to give CaO The balanced equation can be written as- Ca(OH)2 = CaO + H 2O
