WebSep 9, 2024 · So if you start with 20 grams CaCO3 you must end up with a total of 30 grams on the other side. mass CO2 + mass CaO = 30 g. But we can prove that's correct by calculating the mass of each and adding them together. mols CaO = grams/molar mass = 30/100 = 0.3 mols CaCO3 We get 0.3 mol CO2 and 0.3 mol CaO. WebThe molecular weight of calcium carbonate is 100 g per mole. 1 g of calcium carbonate corresponds to 0.01 mole. 1 mole of calcium carbonate contains three oxygen atoms. Thus, 0.01 mole of calcium carbonate will contain 0.03 moles of oxygen atoms which is equal to 0.03×6.02×10 23=1.8×10 22 oxygen atoms. Hence, option B is correct.

CaO (s) + H 2 O (l) ⇌ Ca (OH) 2 (aq) (ΔH r = −63.7 kJ/mol of CaO) As it hydrates, an exothermic reaction results and the solid puffs up. The hydrate can be reconverted to quicklime by removing the water by heating it to redness to reverse the hydration reaction. See more Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term "lime" connotes calcium … See more Calcium oxide is usually made by the thermal decomposition of materials, such as limestone or seashells, that contain calcium carbonate (CaCO3; mineral calcite) in a lime kiln. This is accomplished by heating the material to above 825 °C (1,517 °F), a process … See more Because of vigorous reaction of quicklime with water, quicklime causes severe irritation when inhaled or placed in contact with moist skin or eyes. Inhalation may cause coughing, … See more • Lime Statistics & Information from the United States Geological Survey • Factors Affecting the Quality of Quicklime See more • The major use of quicklime is in the basic oxygen steelmaking (BOS) process. Its usage varies from about 30 to 50 kilograms (65–110 lb) per ton of steel. The quicklime neutralizes the acidic oxides, SiO2, Al2O3, and Fe2O3, to produce a basic molten slag. See more Calcium oxide is also a separate mineral species (with the unit formula CaO), named 'Lime'. It has an isometric crystal system, and can form a solid solution series See more WebFinally, on the reactant side, we have three oxygen atoms. And on the product side, we have one oxygen atom in CaO plus two oxygen atoms in CO2 for a total of three oxygen atoms …
