The chemical equation Cu + 2NH3 -> Cu(NH3)2

1. Detailed Information about the Cu + 2NH₃ -> Cu(NH₃)₂Equation

This equation describes the reaction between copper (Cu) and ammonia (NH₃) to form the ammonia complex of copper [Cu(NH₃)2].

2. Reaction Conditions

For the reaction to take place, copper and ammonia need to be introduced into a suitable reaction environment. Ammonia is usually in gas form and copper is typically solid, so specific conditions may require certain temperature and pressure.

3. Reaction Process

The copper atom (Cu) reacts with 2 ammonia molecules (NH₃) to form the complex [Cu(NH₃)2]. This is a complex process in which copper and ammonia combine through chemical bonds.

4. Phenomena Occurring

The specific phenomena can vary depending on the particular conditions of the reaction, but a common occurrence when copper reacts with ammonia is a color change. Copper usually has a reddish-brown color, but when combined with ammonia, it can produce a substance that is blue or green, which is [Cu(NH₃)2].
