|Reactions : Common Decomposition Reactions|
A common characteristic of decomposition reactions is that they occur when a solid substance is heated.
1. Calcium carbonate is strongly heated in a test tube.
2. A sample of magnesium carbonate is heated.
3. Ammonia carbonate is heated.
4. Sodium bicarbonate is heated.
5. Sodium chlorate is heated in the presence of a catalyst.
6. A sample of potassium chlorate is heated in the presence of manganese dioxide.
7. A sample of solid potassium nitrate is heated.
8. Carbonic acid decomposes.
9. A solution of hydrogen peroxide reacts in the presence of manganese dioxide.
10. Water is electrolyzed.
