Q15E - Chemistry (OpenStax)

Question

Write an equation for the reduction of cesium chloride by elemental calcium at high temperature.

 

Step-by-Step Solution

Answer

The equation for the reduction of cesium chloride by elemental calcium at high temperature is:

\(2CsCl(s) + Ca{(s)_{}} \overset{▲}{\rightarrow} CaC{l_2}(s) + 2Cs(s)\)

Step 1: Occurrence and preparation of the representative metals

• The majority of metals exist in nature in either their free or mixed states. 
• When a metal is discovered in nature in its metallic form, it is considered to occur in free state. 
• Metals exist in combined form as compounds with other elements, most of which are non-metallic.

Step 2: Equation for the reduction of cesium chloride by elemental calcium at high temperature

Cesium gets replaced by calcium and forms calcium chloride in the presence of heat. Cesium is separated as a solid product.

 

The balanced equation for the reduction of cesium chloride by elemental calcium at high temperature is:

\(2CsCl(s) + Ca{(s)_{}} \overset{▲}{\rightarrow} CaC{l_2}(s) + 2Cs(s)\).
