Asked Oct 9, 2019

A solid piece of aluminum is added to a test tube containing a solution of iron (II) chlorate [Fe(ClO3)2]. The piece of aluminum begins to darken in color, and the test tube becomes warm to the touch (evidence of chemical change).

(a) write the balanced molecular equation that happened in the test tube.

(b) which metal was oxidized

(c) which metal was reduced

Expert Answer

Step 1

The balanced molecular equation that happened in the test tube can be written as

This is a single replacement reaction

2A1+ 3Fe(C1O)2>2A1(CIO;);+3Fe

Step 2

Metal oxidized

Initially (Reactant side) the oxidation sate of Aluminium is 0 but the product side is Al3+

Hence, the a...
