Thermodynamics- Enthalpy of Reaction and Hess’s Law Objectives: 1. To calculate the heat of reaction of a given reaction using the concepts derived from Hess’s Law. Pre-lab Questions: 1. Define Heat of Reaction. The enthalpy change associated with the completion of a chemical reaction. 2. Define Specific Heat. The energy it takes to raise the temperature of 1 gram of a substance by one degree Celsius. 3. Calculate the heat of reaction assuming no heat is lost to the calorimeter. Use correct

To earn an outcome point for the laboratory report‚ a student must submit a formal lab report that earns a score of at least 90/100. Each error (factual‚ grammatical‚ typographical‚ spelling) results in a deduction of 5/100. Several opportunities will be offered through the second half of the semester for students to submit a successful

The main objective of this lab is to see if the rate of cellular respiration will be affected if we change the food source from glucose to three different experimental variables (fructose‚ sucrose‚ lactose). Cellular Respiration is a process that generates ATP and it involves the complete breakdown of glucose to carbon dioxide and water. Carbohydrates‚ fats‚ and proteins can all be used as fuels in cellular respiration‚ but glucose is most commonly used as an example to examine the reactions and
