All done with thermo! Now you need to demonstrate your understanding of these topics. Agenda No Warm Up 89 HW Check – Topic 7 Review Padlet Problems Exam 7 Homework Post Day 87-89 Summaries in OneNote Enjoy your weekend. Get some sleep 🙂
Now that we’ve seen everything in the course, we are going to do some FRQ practice in electrochem to prepare for the exam. Agenda Warm Up 88 An electrolytic cell is created with molten zinc chloride. The cell is run at 3.50 amps for 2.00 hours. (a) Sketch this cell […]
It’s time to practice our new heating curve skills! Agenda Warm Up 88 (1)Observe the demonstration. Describe what is happening before and after we stop heating the flask. (2)Now observe the second step. Sketch an image of the apparatus before and after we put the ice on the flask. Describe […]
We are going to wrap up our AP Chem content today. The final concept we will explore is that of cells in non-standard conditions and electrolytic cells. Agenda Warm Up 87 Magnesium metal will react with acid (hydrogen ions) in a vigorous reaction. (a) Write the cell diagram for this […]
Our final concept in the thermochemistry unit is that of the energy of heating and cooling through phase transitions. Today you will learn how to break these heating problems into parts so we can find the total energy absorbed or released in the heating or cooling. Agenda Warm Up 87 […]
You are going to finish up your Lab today and submit it to peergrade. We will also begin looking at phase changes. Agenda NO WARM UP Preview the rubric then turn in Lab 7.2 – Calorimetry Watch videos and take notes on heating curves (intro)(problems) Homework Complete your Lab 7.2 […]
Now that we have determined the thermicity of several dissolving salts, we will find the enthalpy for some metal-acid displacements. Agenda Warm Up 85 (15 min) What are the key concepts presented in topic 7.2? Write them down. What do we know about the energy absorbed by one substance and […]
Today we will have the opportunity to use a nested-cup calorimeter to explore heat of two processes: dissolving of crystals and metal-acid displacements. Agenda Warm Up 84 (30 min) What measurements are essential to determine the enthalpy (kJ/mol) for a salt dissolving? What do these measurements let us calculate? (be […]
Now that we have an idea about calorimetry, we will go into more depth on enthalpy. Agenda 7.2 Practice Q&A Discussion 7.2 – Calorimetry & Enthalpy Specific Heat and Calorimetry Drills Homework Finish Practice 7.2 on MyOpenMath Read through the background and paraphrase the purpose and procedures of Lab 7.2a […]
Now that we understand how energy is transferred between objects and we can calculate that energy using specific heat, we will extend this to calorimetry problems. In addition, today we introduce the concept of enthalpy. Agenda Warm Up 82 1. Which way does energy always flow between a hot object […]
