Calcium solid is placed in a solution of iron (III) chloride producing calcium chloride and iron solid

mestny [16]

Answer:

3Ca₍s₎ + 2FeCl₃ -------------------------------------------------------------> 3CaCl₂ + 2Fe₍s₎.

Explanation:

Iron(III) chloride is also known as Iron trichloride and it has the molar mass value of 162.2 g/mol and density of 2.9 g/cm³.

The balanced equation for the chemical reaction between solid calcium and iron (III) chloride is given below as:

3Ca₍s₎ + 2FeCl₃ -------------------------------------------------------------> 3CaCl₂ + 2Fe₍s₎.

This kind of chemical reaction is known as single displacement reaction or single replacement reaction.
