The equation 2CrBr3 + 3S -> 2CrS3 + 6HBr

  1. Detailed information about the equation: The equation demonstrates the chemical reaction between Chromium bromide (CrBr3) and Sulfur (S) to produce Chromium sulfide (CrS3) and Hydrobromic acid (HBr).

  2. Reaction conditions: This reaction typically occurs at high temperatures.

  3. Reaction Process: When two moles of Chromium bromide are heated with three moles of Sulfur, they form two moles of Chromium sulfide and six moles of Hydrobromic acid. This reaction is a single replacement reaction, in which Chromium bromide is replaced by Chromium sulfide.

  4. Phenomena occur: During the reaction process, color changes can be observed. Chromium bromide is dark green or black, while Chromium sulfide is reddish-brown. Additionally, there will be a release of heat and bromide gas.
