Lesson 1: Sorting Chemical Reactions

Last updated over 2 years ago
5 questions
Phenomenon: There are many different kinds of pollutants that come from different places and different chemicals. There are different types of chemical reactions that create different products.

Part 1: Equation Sort Patterns Challenge

How can patterns in chemical equations help us organize them into categories?
Required
1

Challenge: Sort the “equations” in Set #1 into up to five (5) different categories.

Rules:
  • There must be at LEAST 3 equations in each group
  • Equal sign location matters. 1 + 2 = 3 cannot be in the same group as 3 = 1 + 2

  • 1 + 2 = 3
  • 22 + 55 = 25 + 52
  • 6 = 4 + 2
  • A + B = C
  • C = A + B
  • AB + CD = AD + BC
  • AB + C = AC + B
  • 🌲🔥+ 🌬= 🌲🌬 + 🔥🌬
  • 👗🙍 + 👠 = 👗👠 + 🙍
  • 😀 + 💛 = 😍
  • ⛄🎿 + 🏂🏔 = ⛄🏔 + 🏂🎿
  • 21 + 5 = 25 + 1
  • ☔ =🌻 + 💐
  • CH + O = CO + HO
  • 10 + 1 = 11 + 01

  • Category 2
  • Category 3

Report:
Click on the figure to expand it. In your journal, create a table like in the figure. For each of your categories that you made above, give it a name (example: reactions that are adding two things together could be called "combination"), a simple description, and two example equations that fall under that category.

Part 2: Chemical Equations Challenge
Required
1

Challenge:
Sort the chemical equations in Set #2 into up to five (5) different categories.
Rules:
  • There must be at LEAST 3 equations in each group
  • Arrow location matters. 1 + 2 → 3 cannot be in the same group as 3 → 1 + 2

  • Ag2S + Al → Al2S3 + Ag
  • SO2 + O2 → SO3
  • CO + O2 → CO2
  • H2CO3 → CO2 + H2O
  • CaCO3 + H2SO4 → H2CO3 + CaSO4
  • ZnS + 3O2 → ZnO + 2SO2
  • NO2 + H2O + O2 → HNO3
  • Cu + H2SO4 → CuSO4 + H2
  • H2O2 → H2O + O2
  • Na3PO4 + Al2(SO4)3→ Na2SO4 + AlPO4
  • Ca + 2H2O → Ca(OH)2 + H2
  • H2SO4 → SO3 + H2O
  • BaCl2 + MgSO4 → BaSO4 + MgCl2
  • CH4 + O2 → H2O + CO2
  • C8H18 + O2 → H2O + CO2
  • Category 1
  • Category 2
  • Category 3
  • Category 4
  • Category 5

Report:
Click on the figure to expand it. Create another table like in the figure, including the named categories and then complete the table with the equations in Set #2. What do you think each category means? Next you will check your work!

Watch the video on Types of Chemical Reactions.

Reflect: What are the 5 types of chemical reactions, were you right? Go back to your categories in #3 and #4 and see how you did! Put a star next to the categories you got right! Also, this video showed one additional type: Acid-Base Reactions (we might get to the later!).
