Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
![**Question:**
Copper (II) perchlorate undergoes a double displacement reaction with ammonium phosphate. Write the balanced equation.
**Answer:**
To write the balanced chemical equation for the double displacement reaction between Copper (II) perchlorate and ammonium phosphate, follow these steps:
1. **Write the formulas for the reactants:**
- Copper (II) perchlorate: \(\text{Cu(ClO}_4\text{)}_2\)
- Ammonium phosphate: \((\text{NH}_4)_3\text{PO}_4\)
2. **Write the formulas for the products:**
- Copper (II) phosphate: \(\text{Cu}_3(\text{PO}_4)_2\)
- Ammonium perchlorate: \(\text{NH}_4\text{ClO}_4\)
3. **Combine and write the unbalanced equation:**
\[
\text{Cu(ClO}_4\text{)}_2 + (\text{NH}_4)_3\text{PO}_4 \rightarrow \text{Cu}_3(\text{PO}_4)_2 + \text{NH}_4\text{ClO}_4
\]
4. **Balance the equation:**
\[
3\text{Cu(ClO}_4\text{)}_2 + 2(\text{NH}_4)_3\text{PO}_4 \rightarrow \text{Cu}_3(\text{PO}_4)_2 + 6\text{NH}_4\text{ClO}_4
\]
Therefore, the balanced equation is:
\[
3\text{Cu(ClO}_4\text{)}_2 + 2(\text{NH}_4)_3\text{PO}_4 \rightarrow \text{Cu}_3(\text{PO}_4)_2 + 6\text{NH}_4\text{ClO}_4
\]
In this balanced equation, you can see that the number of atoms for each element is equal on both sides, satisfying the law of conservation of mass.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F9feb948d-7f0e-4488-9fa7-4d9b218ef655%2Fb8304874-abcd-42a3-bec0-97c81587dbab%2Fv2absqo_processed.jpeg&w=3840&q=75)
