Identifying the Element 'X' and the Compound Formed:
Element 'X':
- The element 'X' in this scenario is most likely copper.
Compound Formed:
- When copper (element 'X') is heated in air, it reacts with oxygen to form copper oxide, which is black in color.
Explanation:
- When copper is heated in the presence of oxygen, it undergoes oxidation to form copper oxide (CuO). This reaction is represented by the equation: 2Cu + O2 → 2CuO.
- Copper oxide is a black colored compound due to the presence of copper in the +2 oxidation state.
- This change in color from brown to black is a result of the formation of copper oxide on the surface of the copper metal during the heating process.
