Question
**Educational Content on Alcohol Fermentation and Enthalpy Calculations** **Introduction to Alcohol Fermentation** In winemaking, glucose (\(C_6H_{12}O_6\)) undergoes fermentation to produce ethanol (\(C_2H_5OH\)) and carbon dioxide (\(CO_2\)). This process can be represented by a balanced chemical equation, which you are tasked to formulate. **Part A: Writing a Balanced Chemical Equation** To express the chemical reaction for alcohol fermentation, input your balanced equation, including the phases of each substance, into the form provided. Ensure all atoms are accounted for on both sides of the equation. For example: - Glucose: \(C_6H_{12}O_6(s)\) - Ethanol: \(C_2H_5OH(l)\) - Carbon Dioxide: \(CO_2(g)\) **Part B: Calculating the Standard Enthalpy Change (\(\Delta H^\circ_{rxn}\))** In this section, calculate the standard enthalpy change (\(\Delta H^\circ_{rxn}\)) for the reaction. Use the given standard heats of formation: - \(C_6H_{12}O_6(s)\): \(-1273.3 \, \text{kJ/mol}\) - \(CO_2(g)\): \(-393.5 \, \text{kJ/mol}\) - \(C_2H_5OH(l)\): \(-277.6 \, \text{kJ/mol}\) Enter your calculated value in kilojoules, rounded to one decimal place, using the formula for enthalpy change based on the standard heats of formation. --- **Note**: The text also references resources for further study: - *KCV: Determining the Enthalpy of Reaction from Standard Enthalpies of Formation* - *IWE: \(\Delta H^\circ_{rxn}\) and the Standard Enthalpies of Formation* - Section 7.9 in your eText These resources will deepen your understanding of enthalpy calculations in chemical reactions.
