solid CaCo3 is heated and decomposes into solid CaO and CO2 gas. suppose a limekiln of volume 600 L is pressurized with CO2 to 4.4 atm and is heated 580.0 degrees celsius. When the amount of CO2 has stopped changing, it is found that 1.72 kg of CaCO3 have appeared. Calculate the pressure equilibrium constant Kp this experiment suggests for the equilibrium between CaCO3 and CaO at 580.0 degrees celsius. thanks!
QUESTION 3 Solid calcium carbonate (CaCO3) decomposes into solid calcium oxide (Cao) and carbon dioxide (CO) gas according to the following heterogeneous equilibrium: CaCO3(s) = Cao(s) + CO2(g) What is the correct equilibrium constant expression for this equation? OK (CaCO3] [Cao][CO2] ok, = [Coz] [Cao][CO.” [CaCO3] okea 0K = [Cao][CO2] [Ca][CO] (CaCO3] ok
When solid CaCO3 is heated, it decomposes to give solid CaO and CO2 gas. A volume of 360 mL of gas is collected over water at a total pressure of 730 mmHg and 16 ∘C. The vapor pressure of water at 16 ∘C is 14 mmHg. CaCO3(s)→CaO(s)+CO2(g) a) What was the partial pressure of the CO2 gas? Express your answer with the appropriate units. b) How many moles of CO2 gas were in the CO2 gas sample? Express your answer...
CaCO3(s) = Cao (s)+CO2 (g) When heated strongly, solid calcium carbonate decomposes to produce solid calcium oxide and carbon dioxide gas, as represented by the equation above. A 2.0 mol sample of CaCO3(s) is placed in a rigid 100. L reaction vessel from which all the air has been evacuated. The vessel is heated to 898°C at which time the pressure of CO2(g) in the vessel is constant at 1.00 atm, while some CaCO3(s) remains in the vessel. a. Calculate...
CaCO3(s) ⇄ CaO(s) + CO2(g) 0.100 mol of CaCO3 and 0.100 mol CaO are placed in an 10.0 L evacuated container and heated to 385 K. When equilibrium is reached the pressure of CO2 is 0.220 atm. 0.300 atm of CO2 is added, while keeping the temperature constant and the system is allowed to reach again equilibrium. What will be the final mass of CaCO3? 7.47 g 12.54 g 18.01 g 2.00 g 10.01 g
CaCO3 (s) ⇌ CaO (s) + CO2 (g) Given at equilibrium 2.5 g CaCO3; 1.35 g CaO; 3.45 g CO2 in a 1.5 L container at 25˚C.
Upon heating, CaCO3 decomposes to CaO and CO2. What change in the hybridisation of carbon occurs in this reaction? Select one: a. sp to sp2 b. sp2 to sp3 c. sp3 to sp d. sp2 to sp e. sp to sp3 f. None, it is sp2 in both.
When solid calcium carbonate is heated, it decomposes according to the reaction: CaCO3(s) ⇄ CaO(s) + CO2(g) Kp = 0.50 A sample of CaCO3 is placed in a 1.0 L evacuated flask and heated to 830 Celsius. What is the mass of CaO produced when equilibrium is established? Please show all work. a) 0.411 g b) 0.500 g c) 0.00552 g d) 5.3 g e) 0.310 g
When limestone (solid CaCO3) is heated, it decomposes into lime (solid CaO) and carbon dioxide gas. This is an extremely useful industrial process of great antiquity, because powdered lime mixed with water is the basis for mortar and concrete - the lime absorbs CO2 from the air and turns back into hard, durable limestone. Suppose some calcium carbonate is sealed into a limekiln of volume 250. L and heated to 870.0 °C. When the amount of CaCO3 has stopped changing,...
Consider the following reaction: CaO (s) + CO2 (g) → CaCO3 (g) If 12.9 g of carbon dioxide, CO2, react, how many grams of calcium carbonate, CaCO3, are produced?
