The above chemical equation represents the reaction between calcium oxide (CaO) and calcium nitride (Ca3N2), producing calcium oxide and nitrogen (N2) as products. However, this equation is written incorrectly, the correct equation should be:
- Reaction conditions
The reaction conditions mainly depend on the temperature and pressure. This reaction usually occurs when heated.
- Reaction process
When calcium oxide and calcium nitride are placed in the same glass container and heated, it will generate enough heat to start the reaction. The result is the production of calcium oxide and nitrogen.
- Observed phenomena
When the reaction occurs, you can observe the color change of the substance in the glass container from the white of calcium oxide and the dark brown of calcium nitride to the white of calcium oxide. At the same time, you can also notice the escape of nitrogen gas.
