WebThe correct option is C Endothermic and thermal decomposition reaction. The reaction 'Limestone on heating decomposes into quick lime and carbon dioxide gas' can be represented as, CaCO3(s) heat −− → CaO(s)+CO2(g). Heat is absorbed in the reaction, so it is an endothermic reaction. WebMethod: Prepare a tabulated results sheet before starting the experiments. Set a lump of calcium carbonate (limestone) on a gauze. Heat the limestone very strongly for 5–10 minutes. Write down what you observe. (If possible, darken the room and note what happens when the flame is trained directly on the lumps.
WebBased on the molar masses of the reactants and products, this equation tells us that 100.1g of CaCO will decompose completely into 56.1g of CaO and 44.0g of CO. If the limestone used is pure CaCO (which is very rare) then 20 tonnes of that limestone will produce (20/100.1*56.1) = 11.2 tonnes of CaO. WebThe equation for the reaction is H3PO4 (aq)+3OH (aq)3H2O+PO43 (aq) 4-20 Calcium oxide is prepared by heating limestone (calcium carbonate, CaCO3) to a high …

WebAnswer (1 of 2): Limestone is calcium carbonate, CaCO3. Equation for the reaction (thermal decomposition): CaCO3 = CaO + CO2 So, 1 mole of CaCO3 gives 1 mole of CaO on strong heating. Molar mass of CaCO3 = 40 +12 + (16 x 3) = 100 g/mole Molar mass of calcium oxide, CaO = 40 + 16 = 56 g/mole ... rbs 70 argentinaWebCorrect options are A) , B) and C) Option (A) is correct.
