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. WebCalcium is the fifth most abundant metal in the Earth’s crust (4.1%). It is not found uncombined in nature, but occurs abundantly as limestone (calcium carbonate), gypsum …

Example # 02: WebAug 14, 2024 · How many atoms are contained in a unit cell? Each corner atom is shared with eight adjacent unit cells and so a single unit cell can claim only 1/8 of each of the eight corner atoms. Similarly, each of the six atoms centered on a face is only half-owned by the cell. The grand total is then (8 × 1/8) + (6 × ½) = 4 atoms per unit cell. dhh oph louisiana

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 … See more • Lime Statistics & Information from the United States Geological Survey • Factors Affecting the Quality of Quicklime • American Scientist (discussion of C dating of mortar) 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.
