Introduction
Calcium nitride, a compound composed of calcium and nitrogen, is known to decompose into its constituent elements when subjected to heat and electricity. This decomposition process is a crucial aspect of chemistry, as it helps us understand the properties and behavior of various compounds. In this article, we will delve into the decomposition of calcium nitride and identify the products of this process.
The Decomposition Process
Calcium nitride (Ca3N2) is a compound that can be synthesized through various methods, including the reaction of calcium metal with nitrogen gas. When heated or subjected to an electric current, calcium nitride decomposes into its constituent elements. This decomposition process can be represented by the following equation:
Ca3N2 → 3Ca + N2
Products of Decomposition
The products of the decomposition of calcium nitride are calcium metal and nitrogen gas. Calcium metal is a highly reactive element that readily loses two electrons to form a +2 ion. Nitrogen gas, on the other hand, is a colorless, odorless, and tasteless gas that makes up approximately 78% of the Earth's atmosphere.
Analyzing the Options
Now that we have identified the products of the decomposition of calcium nitride, let's analyze the given options:
A. Ca2 + N2 B. Ca + N C. Ca3 + N2 D. Ca + N2
Based on our understanding of the decomposition process, we can eliminate options A and C, as they do not accurately represent the products of the decomposition. Option B is also incorrect, as it suggests that the decomposition produces calcium and nitrogen, but not in the correct proportions.
Conclusion
In conclusion, the decomposition of calcium nitride (Ca3N2) into its constituent elements using heat and electricity produces calcium metal and nitrogen gas. The correct products of the decomposition are represented by the equation Ca3N2 → 3Ca + N2. Therefore, the correct answer is:
D. Ca + N2
