Honors Chemistry 2019-20-2B Assignments

For this last assignment of the year, you'll be writing recipes (and maybe helping around the house by cooking a meal) while keeping chemistry in mind. As you write your recipes, you'll be relating the culinary creation to various chemistry concepts from throughout the year. The instructions are attached.

This is not due until 5/26. I know there are some people who are bored or who will enjoy doing this assignment so I wanted to post it early.

There are a few things here to help you understand equilibrium shifts: 1) Digital Simulation Game (class code cchschem) 2) Slideshow tutorial 3) A video of an equilibrium reaction shifting 4) A worksheet with a key that we normally do in class. I recommend you do the activities in order, but technically none of them individually is required as long as you get the concepts.

Your assignment that I will grade is the Google Form. Do this AFTER doing at least some of the tutorial activities.

Complete this AFTER going through the notes.

Watch this short video about Reaction Rates. This video is really short and good at explaining each of the variables that affect reaction rates. He goes a little more in-depth into how a catalyst works than you need to know, but you still need to know what effect a catalyst has, just not how it works. 

Draw Models for each of these situations. You do not have to draw digital models. You can draw them on paper or a whiteboard and upload a picture to Classroom. You do not have to print this document out. You can use any notebook paper if you're choosing to do this assignment on paper. 

Go through the various simulation settings and answer the questions on the Google Form. Each question will ask about the results of each trial of the simulation and WHY they occured. You may not know the answer for sure, but take your best guess so that I can gauge how much everyone knows before we dive into this topic.

If you have sugar cubes, alka seltzer, or rock salt, get 3 bowls of water and 3 equal amounts of whatever you're using. One trial will be your control, one will test higher surface area, and one will test how temperature affects the reaction rate. Place one whole sugar cube or alka seltzer or one spoonful of rock salt in a bowl of room temp water. Do not stir. Time how long it takes to dissolve. Heat the water in the 2nd bowl up. For your safety, DO NOT BOIL the water. Place the 2nd whole sugar cube, etc. in the water. Record how long it takes to dissolve. Crush your 3rd sugar cube/alka seltzer/spoonful of salt into tiny pieces. Place these in the 3rd bowl of water (at room temp). Record how long it takes to dissolve. 

What do you notice? Do your results show the same as the simulation? 

Draw a model of equal sized pieces of aluminum and iron that are both the same hot temperature and placed into equal amounts of room temp water. Show what happens to the energy in each.

You can either create a digital drawing and attach the file, or draw it on paper and upload a picture.

I have attached a short checklist to remind you of things to include in the model.

Use the digital lab from last week to discover the identity of an unknown metal. Plan your own experiment to solve for the specific heat capacity of the material and compare it to some known metals to figure out which metal it is.

The yellow highlighing are areas you need to edit. The orange highlighted areas are instructions I didn't want you to miss.

Follow the instructions on the lab worksheet and fill out the questions at the end. The link for the digital lab is at the top of the lab worksheet. If you choose to do this assignment on paper, you don't have to print it out. Just write your data table and answers to your question on a piece of notebook paper and upload a picture when you're done.

Read this article and/or watch this video. Complete the matching Google Form when you're done. There's a form for the article and a form for the video.

Complete this Google Form after you've watched the video or read the article about specific heat capacity. There is a key built into the form to help you check your answers.

Make a copy and complete this worksheet digitally or do it on a separate piece of paper and submit a picture or scan. Attach your finished worksheet to this assignment ant turn in.

This was assigned before spring break, you don't have to redo this if you did it once. Make sure you still can perform these calculations though.

Attached you will find an instruction sheet, practice sheet, and key to review what we discussed last class. Contact me with any and all questions you have. I'm also posting the standard enthalpy packet in case you left yours at school.

Read this article if you need to review how to calculate Change in Enthalpy for a Reaction using Standard Enthalpy of Formations. I also posted some info about this before Spring Break that you're welcome to look back at.

This is not an actual quiz. Take a few minutes and test yourself to see how well you understand enthalpy, endothermic, and exothermic. Based on these results, I'll plan more instruction/review for after spring break.

When you submit, you'll get to see all of the answers to know how you did.

Attach your CERs here. Make sure everyone's names are on the document.

Watch the video and take the attached notes for homework. Complete the attached Google Form as practice as well.

Attach your CERs here. Make sure all names are on your document for anyone getting credit.

This is not for an actual grade, but it will be used to see what you remember from previous classes that you'll need to know for this course. Topics that you don't do well on need to be reviewed as soon as possible.
