Gases- Thermal decomposition of Metal Carbonates to produce CO2 0.0 / 5 ? ChemistryGasesIGCSEEdexcel Created by: IsobelfjCreated on: 15-04-18 12:55 What is thermal decomposition? The braking down of a substances into simpler substances when heated 1 of 9 What is Produced when Metal Carbonates are heated ? Carbon Dioxide + Metal Oxide 2 of 9 What is Copper Carbonate? A green powder that easily decomposes 3 of 9 What does Copper Carbonate easily decompose to form ? Carbon Dioxide + Copper (II) oxide 4 of 9 What is the equation for the thermal decomposition of Copper (II) Carbonate CuCO3 (s) -------> CuO (s) + CO2 (g) 5 of 9 What is the word Equation? copper(II) carbonate -----> copper oxide + carbon dioxide 6 of 9 How is the experiment conducted? Copper (II) carbonate is heated then the CO2 gas given off is collected at the bottom of the test tube -because it is dense and sinks to the bottom 7 of 9 What happens to gas collected ? The CO2 is tested by bubbling through lime-water - it will go cloudy if present 8 of 9 What is the colour change in this reaction ? Green Copper (II) carbonate to Black Copper (II) oxide 9 of 9
