What volume of CO_(2) at 0^(@)C and 1 atm is formed by heating 200 g CaCO_(3) ?
10 g of CaCO_(3) contains :
The volume of CO_(2) at STP obtained by heating 1 g of CaCO_(3) will be
Active mass of 5.6 g CaO(s) is
Calculate the mass of lime (CaO) obtained by heating 200kg of 95% pure lime stone (CaCo_3) :
Quick lime: (CaO) is produced bu heating limestone (CaCO_(3)) to derive off CO_(2) gas. CaCO_(3) (s) rarr CaO(s) +CO_(2)(g), Delta_(r)H^(Theta) = 180 k J mol^(-1), Delta_(r)S^(Theta) = 150 J K^(-1) Assuming that variation fo enthalpy change and entropy change with temperature to be negligible, which of the following is correct?
How many grams of calcium oxide is obtained on heating 100 g of CaCO_(3)(s) ?
10 grams of CaCO_(3) is completely decomposed to x and CaO. 'x' is passed into an aqueous solution containing 0.1 mole of sodium carbonate. What is the number of moles of sodium bicarbonate formed? (mol. wts: CaCO_(3) = 100, NaCO_(3) = 106, NaHCO_(3) = 84 )
Calculate the weight of lime (CaO) obtained by heating 250kg of 90% pure lime stone ( CaCO_3 ). CaCO_3→CaO+CO_2
