2 With strong heating, calcium carbonate undergoes thermal decomposition: CaCO, (s) CaO (s) + CO2 (a) Write a word equation for the change.(b) How many moles of CaCO, are in 50 g of calcium carbonate? (A: Ca = 40, C = 12, O = 16.) (c)iWhat mass of calcium oxide is obtained from the thermal decomposition of 50 g of calcium carbonate, assuming a 40% yield? i (ii)What mass of carbon dioxide will be given off at the same time? (iii )What volume will this gas occupy at rtp?​
