Answer:
2.13 V
Explanation:
The balanced equation of the reaction his;
2Cr^3+(aq) + 3Ca(s) -----> 2Cr(s) + 3Ca^2+(aq)
Since this is a galvanic cell then E°cell must be positive. It implies that calcium will be the anode and chromium will be the cathode since calcium is ahead of chromium in the electrochemical series.
E°anode= -2.87 V
E°cathode= -0.74 V
E°cell= E°cathode -E°anode
E°cell= -0.74 -(-2.87)
E°cell = 2.13 V

Explanation:
The collision and decomposition of 2 ammonium nitrate molecules results in the formation of 2 molecules of
and 4 molecules of 
<h3>Decomposition reaction</h3>
Ammonium nitrate decomposes to produce nitrous oxide and water according to the following equation:

In the above, a mole of ammonium nitrate decomposes to form a mole of nitrous oxide and 2 moles of water.
If moles of ammonium nitrate decomposes, the equation becomes:

Thus, 2 moles of nitrous oxide and 4 moles of water would be formed.
