Learning Competency The learners would be able to Balance Redox reactions using the change in oxidation number method. (STEM_GC11ABIVF-g-170) Activity 1: INSPECT AND BALANCE Directions: Inspect very weli the given chemical reactions and balance the reaction. If the reaction is already balanced, just write the word balance beside the equation. This will serve as your review in balancing chemical reactions. 1. NasPO4 +KOH-> NAOH + K&PO4 LizCO3 M9CO3 +LiF 2. P4+ O2 AgNO3+ CF4+ 3. P203 4. Cu Cu(NO3)2 + Ag F2 5. Br2> CBr+ GaF3+ Cs CsF+ Ga H2 NH3 HCI H2+ AICI3 NF3 10. NaF+Br2NaBr+ F2 6. 7. N2 + Al+ N2+F2 8. 9. Activity 2: BALANCING REDOX REACTIONS Directions: Inspect the given reactions very carefully, follow the given step- by-step procedure to balance the equation. 1.
