4. When CaO is mixed with water and broken down into a powder, this powder is called (slaked lime); it is also known as (calcium hydroxide). This process is referred to as the (slaking process), and the chemical equation for it is (CaO + H2O = Ca(OH)2). The aqueous solution of this product is called (limewater). 5. The three conditions that must be present simultaneously for combustion are (fuel), (oxidizer), and (ignition source). 6. The common fuels used for calcining limestone are (coke) and (anthracite).
Slaked lime, quicklime, hydrolysis, CaO+H2O=Ca(OH)2; combustion products, oxygen, ignition point; coal, natural gas
4. Slaked lime, quicklime; slaking process: CaO + H2O ---- Ca(OH)2; lime milk. 5. Combustibles, oxidizers, ignition sources. 6. Coke, anthracite
4. Slaked lime, quicklime; slaking process: CaO + H2O ---- Ca(OH)2; lime milk. 5. Combustibles, oxidizers, ignition sources. 6. Coke, anthracite
Slaked lime, quicklime; digestion process: Ca + H2O = Ca(OH)2; lime milk; combustibles; oxidizers; ignition sources; coke; anthracite
1. Slaked lime, quicklime, slaking process, CAO+H2O---CA(OH)2, lime milk 2. Combustibles, oxidizers, ignition sources 3. Coke, anthracite
Is it a bonus point? If there are bonus points, I’ll come and answer every day
4. Slaked lime, quicklime; digestion process: CaO + H2O -- Ca(OH)2; lime milk. 5. Combustible materials, oxidizing agents, ignition point. 6. Coke, anthracite. 1# chen3jun
