Section 5: Read pages 285-287 of your textbook, then answer questions 1-4 on page 287.
All: Some of you requested extra videos for studying - here to you go:
Solving Chemical Reactions - Predicting the Products
Writing and Balancing Reactions Predicting Products
Also, don't forget about your textbook! Chapter 8 has everything you need to know!

Sections 2H & 4: Write and balance the reaction equations for the problems below. The given information is the reactants side of each equation. Use the new tables you got today to include states of matter (all!); if the reaction is not possible, you should write 'DNR' on the products side of the arrow (you still still write out the reactants side with states of matter).
1. silver nitrate + nickel
2. iron + aluminum oxide
3. lead + zinc acetate
4. sodium bromide + iodine
5. aluminum bromide + chlorine
6. calcium + hydrochloric acid
7. sodium + water (this one is very tricky! think about how water can be written as an ionic compound - cation + anion...)
**STUDY - we will have a quiz on this next week!**

All: Sorry I couldn't be at school with you today but I will be back tomorrow. I know some of you are feeling a little shaky on balancing, so here are two more videos to help you out. The first is more of an introductory video, while the second goes through more challenging balancing problems step-by-step.
Introduction to Balancing Chemical Equations
Balancing Chemical Equations Practice Problems
Also, here is a simulator that you may find helpful as well: https://phet.colorado.edu/en/simulation/balancing-chemical-equations
Finally, don't forget about your textbook! It is a valuable resource and has lots of information about balancing chemical equations.
Section 5: You are to complete the balancing worksheet found under 'Homework Documents' and write the word equations (in your notebook) for the equations in numbers 1, 3, 4, 5 & 6.
Section 4: Balance the following equations in your notebook:
1. Na + H2O → NaOH + H2
2. Fe + FeCl3 -→ FeCl2
3. Ba(OH)2 + AlCl3 → Al(OH)3 + BaCl2
4. MgCl2 + NaOH → Mg(OH)2 + NaCl
5. AgNO3 + CuCl2 → AgCl + Cu(NO3)2
6. ZnS + O2 → ZnO + SO2
7. Na + H2O → H2 + NaOH
8. BaCl2 + (NH4)2CO3 → BaCO3 + NH4Cl
9. KI + Cl2 → KCl + I2
10. Pb(NO3)2 + HCl → PbCl2 + HNO3

Due Next Class (Monday or Tuesday 2/8 or 2/9)
All: Complete your lab! For the postlab: you know four sets of reactants...match them to the correct products in question #1! Once you've figured out which reactants and products go together, fill in the blank space with chemical formulas (NOT words).
Also, watch the first 9:12 seconds of the video below (it will help solve the mystery of those numbers in front of our chemical compounds):
A Beginner's Guide to Balancing Equations
Then, try to balance #2 & 4 on your word equations worksheet.
