5 Lucy heats some calcium carbonate. She weighs the reaction vessel at the
start of the reaction and again after it has been heated. Calcium carbonate decomposes into calcium oxide and carbon dioxide.
Look at Lucy's results:
Mass of calcium carbonate before heating = 2.00 g
Mass of calcium oxide left after heating = 1.129
Calculate the mass of carbon dioxide that was released during the
decomposition. Show all your workings.
