3.5.2 Metal Carbonate decomposition Flashcards
1
Q
What is thermal decomposition?
A
Thermal decomposition is when heat energy is used to break down a sustance.
2
Q
What do metal carbonates thermally decompose to produce?
A
Metal oxide and Carbon dioxide
3
Q
Metal carbonate —>
A
Metal oxide + carbon dioxide
4
Q
What is downward delivery in thermal decomposition of metal carbonates?
A
Carbon dioxide is denser than air, so it is often collected by downward delivery. This means it sinks to the bottom of a tube and stays there until used.
