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.
![The image provides a diagrammatic representation of the compound aluminum oxide (\( \text{Al}_2\text{O}_3 \)).
### Diagram Explanation:
1. **Elements Involved**:
- **Al**: Represents aluminum atoms.
- **O**: Represents oxygen atoms.
2. **Connections**:
- Each aluminum (Al) atom is connected by arrows to surrounding oxygen (O) atoms, indicating bonds.
3. **Bonding Visualization**:
- On the left, three aluminum atoms are shown connecting to oxygen atoms. This illustrates how aluminum forms connections with oxygen to create aluminum oxide.
- Each oxygen atom is surrounded by a ring of small green squares, possibly symbolizing electron pairs or charges involved in bonding.
4. **Final Structure**:
- On the right, a formatted chemical structure shows two aluminum (\( \text{Al} \)) atoms connected vertically and three oxygen (\( \text{O} \)) atoms in series to depict the molecular formula \( \text{Al}_2\text{O}_3 \).
This diagram provides a simple visualization of how aluminum and oxygen atoms combine to form aluminum oxide through chemical bonds, emphasizing the \( \text{Al}_2\text{O}_3 \) stoichiometry.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F9472d96e-c21a-4060-8ee0-f9ef08d06107%2Fe57a2be8-6815-41f9-b674-a5ae8e6a8371%2Fxvspcc_processed.jpeg&w=3840&q=75)
