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
