Calculate the standard entropy of reaction at 25 ?C for the decomposition of calcium carbonate: CaCO3(s)?CaO(s)+CO2(g)
In the reaction, CaCO3(s)⟶CaO(s)+CO2(g) how many liters of carbon dioxide, CO2, measured at STP, would be produced from the decomposition of 309 g of calcium carbonate, CaCO3?
During the centuries following the collapse of the western Roman Empire, marble (calcium carbonate, CaCO3) was taken from the monuments of Rome and heated to form quicklime (calcium oxide, CaO), which was used to make plaster. Carbon dioxide, CO2, was also produced in this decomposition reaction. Write the balanced equation for this reaction.
The decomposition of calcium carbonate is given by the equation, CaCO3(s) →CaO(s) + CO2(g). Determine if the reaction is spontaneous at room temperature, given the following thermodynamics parameters: Δ? = 178 kJ/mol Δ? = 163 J/Kmol
Calcium oxide and carbon dioxide react to form calcium carbonate, like this: CaO(s)+CO,(g)→ CaCO3(s) At a certain temperature, a chemist finds that a 2.5 L reaction vessel containing a mixture of calcium oxide, carbon dioxide, and calcium carbonate at equilibrium has the following composition: compound amount CaO | 20.5 g CO2 17.1 g CaCo3 66.7 g Calculate the value of the equilibrium constant K for this reaction. Round your answer to 2 significant digits. K = 0 xs ?
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 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.

When heated, calcium carbonate decomposes to yield calcium oxide and carbon dioxide gas via the reaction CaCO3 ---> CaO + CO2 How many grams of calcium carbonate are needed to produce 73.0 of carbon dioxide at STP?
When calcium carbonate is added to hydrochloric acid, calcium chloride, carbon dioxide, and water are produced. CaCO3(s) + 2 HCl(aq) → CaCl2 (aq) + H2O(1) + CO2(g) How many grams of calcium chloride will be produced when 27.0 g of calcium carbonate is combined with 11.0 g of hydrochloric acid? mass of CaCl, g Which reactant is in excess? Cacoz HCI How many grams of the excess reactant will remain after the reaction is complete? mass of excess reactant:
Calcium oxide can be used to "scrub" carbon dioxide from air. Cao(s) + CO2(g) - CaCO3(s) What mass of CO2 could be absorbed by 1.31 g of Cao? What volume would this CO2 occupy at STP?
