An acid anhydride reacts with water to form an acid; e.g., sulfur trioxide, SO 3, reacts with water to form sulfuric acid, H 2 SO 4. Terms in this set (30) CaO + H₂O --> Ca(OH)₂. Calcium oxide reacts with water to form calcium hydroxide. As the monoxide of the alkaline earth metal reacts with water vigorously to form the respective metal hydroxide. KCET 2014: A metallic oxide reacts with water to form its hydroxide, hydrogen peroxide and also liberates oxygen. Which among the following is (are) true about slaking of lime and the solution formed ? Sciences, Culinary Arts and Personal Properties Chemical. Anhydrides of organic acids have many uses. calculate the enthalpy change for the reaction per mole of cao. The reaction of calcium oxide with water to form calcium hydroxide is CaO + H2O -> Ca(OH)2 One molecule of calcium oxide reacts with one molecule of water to form one molecule of calcium hydroxide If 6.50 g CaO is CaO + H2O ---> Ca(OH)2 is balanced and it's the only correct answer. It can react in many different ways, two examples are: Calcium oxide is used to obtain building material because when it is mixture with water can reacts to form calcium hydroxide, which rapidily forms a harden material: CaO + H 2 O → Ca(OH) 2. Chemistry Chemical Reactions Chemical Equations. Calcium Oxide, CaO, reacts with water to form Ca (OH)2 − −. Sodium reacts with fluorine to form sodium fluoride. All rights reserved. Assume that the specific heat capacity of the solution is 4.18 J/g⋅K Potassium reacts with iodine to form potassium iodide. Calcium oxide reacts with a few drops of water to form calcium hydroxide, which is an alkali. Calcium is also an alkaline earth metal whose oxide, calcium oxide reacts with water to produce calcium hydroxide. MgO + SO₃ --> MgSO₄. Calcium oxide reacts with water to form calcium hydroxide, also called slaked lime. 43.1 °C. Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca() 2.It is a colorless crystal or white powder and is produced when quicklime (calcium oxide) is mixed or slaked with water.It has many names including hydrated lime, caustic lime, builders' lime, slack lime, cal, and pickling … & Now, if you believe it is the wrong answer and you intend to continue your search for what you believe to be the correct answer, then y'all have a wonderful time.
