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.
![**Title: Calculating the Specific Heat of Bronze Using a Coffee Cup Calorimeter**
**Introduction**
Understanding specific heat is crucial in material science and thermodynamics. In this tutorial, we will calculate the specific heat of bronze using a coffee cup calorimeter. Let's start with the necessary data and formulas, followed by detailed steps for calculations.

**Data Table: Bronze Data (5 pts)**
| Parameter | Value |
|--------------------------|----------------|
| Mass of Metal (Bronze) | 19.9797 g |
| Temperature of Metal (\(T_{\text{metal}}\)) | 200°C |
| Mass of Water | 150.00 g |
| Temperature of Water (\(T_{\text{H2O}}\)) | 25.00°C |
| Final Temperature (\(T_{\text{water & metal}}\)) | 27.32°C |

**Calculations**
*You must show all work here.*
1. **Calculate \(Q_{\text{H2O}}\)**
Formula:
\[
Q_{\text{H2O}} = m_{\text{H2O}} \times SH_{\text{H2O}} \times \Delta T
\]
Where \(Q_{\text{H2O}}\) is the heat absorbed by water, \(m_{\text{H2O}}\) is the mass of water, \(SH_{\text{H2O}}\) is the specific heat of water, and \(\Delta T\) is the change in temperature.
2. **Calculate the Specific Heat of Bronze**
The formula for the heat balance:
\[
Q_{\text{H2O}} = -Q_{\text{metal}}
\]
This implies:
\[
q_{\text{metal}} = m_{\text{metal}} \times SH_{\text{H2O}} \times \Delta T_{\text{metal}}
\]
*Specific Heat of Metal (\(SH_{\text{metal}}\)):*
\[
SH_{\text{metal}} = \frac{q_{\text{metal}}}{m_{\text{metal}} \times \Delta T} = \frac{19.9797 \, \text{g} \times (27.32 - 200.00)°C}{J/g°C}
\]
