Answer:
C) The products have more energy stored in their chemical bonds.
Explanation:
In such reactions that absorb energy, the products have more energy stored in their chemical bonds.
For endothermic changes, heat is absorbed from the surrounding hence the surrounding becomes colder at the end of the changes.
The heat energy level of the products is higher than that of the reactants.
- Exothermic reactions releases heat to the surroundings. The sum of heat contents of the products is less than that of the hat contents of the reactants.
- Examples of such processes are burning and dissolution.

2 Li(s) +Cl₂→ 2 Li⁺ (aq) + 2Cl⁻ (aq)
The cell potential of the reaction above is +4.40V
<em><u>calculation</u></em>
Cell potential =∈° red - ∈° oxidation
in reaction above Li is oxidized from oxidation state 0 to +1 therefore the∈° oxid = -3.04
Cl is reduce from oxidation state 0 to -1 therefore the ∈°red = +1.36 V
cell potential is therefore = +1.36 v -- 3.04 = + 4.40 V
