Lesson 7
Enthalpy Calculations
Learning Intention: Process how to do two step enthalpy calculations.
Success Criteria
9. I can complete two step enthalpy related calculations that use the heat capacity of water.
A = one step of the calculation correct OR correct process with two errors.
M = correct process for calculation with one error.
E = correct answer with units and 3 sig fig.
Learning Tasks
Do Now (Day 1): Why does a chemical reaction that produces water in the gas state releases less energy than the same same reaction with water being produced in the liquid form?
Listen to Ms Garlick's notes on two step enthalpy calculations. There are three versions of this question, Ms Garlick will do the heating water example by using the 2022 Exam Question 1c (Blank 2022 Exam, 2022 Marking Schedule).
Mahi Choice
