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
