  1. Balancing equationsNo2 - Balancing equations made easy

  2. Here is an equation that needs to be balanced: • KNO3 KNO2 + O2 Step 1: list all the elements neatly under the arrow K N O

  3. Here is an equation that needs to be balanced: • KNO3 KNO2 + O2 K N O Now add up how many K N and O you have on each side

  4. Here is an equation that needs to be balanced: • KNO3 KNO2 + O2 1 K N O Now add up how many K N and O you have on each side

  5. Here is an equation that needs to be balanced: • KNO3 KNO2 + O2 1 1 K N O Now add up how many K N and O you have on each side

  6. Here is an equation that needs to be balanced: • KNO3 KNO2 + O2 1 1 K N O Now add up how many K N and O you have on each side

  7. Here is an equation that needs to be balanced: • KNO3 KNO2 + O2 1 1 K N O 1 Now add up how many K N and O you have on each side

  8. Here is an equation that needs to be balanced: • KNO3 KNO2 + O2 1 1 K N O 1 1 Now add up how many K N and O you have on each side

  9. Here is an equation that needs to be balanced: • KNO3 KNO2 + O2 1 1 K N O 1 1 Now add up how many K N and O you have on each side

  10. Here is an equation that needs to be balanced: • KNO3 KNO2 + O2 1 1 K N O 1 1 3 Now add up how many K N and O you have on each side

  11. Here is an equation that needs to be balanced: • KNO3 KNO2 + O2 1 1 K N O 1 1 2 + 2 = 4 3 Now add up how many K N and O you have on each side

  12. Here is an equation that needs to be balanced: • KNO3 KNO2 + O2 1 1 K N O 1 1 3 4 K and N are fine BUT O is not balanced

  13. Here is an equation that needs to be balanced: • KNO3 KNO2 + O2 1 1 K N O 1 1 3 4 We need more O on the left hand side We only want 1 more O BUT we can only have 1KNO3, or 2KNO3 or 3KNO3

  14. Here is an equation that needs to be balanced: • KNO3 KNO2 + O2 1 1 K N O 1 1 3 4 Lets see what happens if we have 2KNO3 on the left

  15. Here is an equation that needs to be balanced: Lets see what happens if we have 2KNO3 on the left • 2KNO3 KNO2 + O2 1 K N O 1 4

  16. Here is an equation that needs to be balanced: Lets see what happens if we have 2KNO3 on the left • 2KNO3 KNO2 + O2 2 1 K N O 1 4

  17. Here is an equation that needs to be balanced: Lets see what happens if we have 2KNO3 on the left • 2KNO3 KNO2 + O2 2 1 K N O 1 2 4

  18. Here is an equation that needs to be balanced: Lets see what happens if we have 2KNO3 on the left • 2KNO3 KNO2 + O2 2 1 K N O 1 2 4 2 x 3 = 6

  19. Here is an equation that needs to be balanced: Lets see what happens if we have 2KNO3 on the left • 2KNO3 KNO2 + O2 2 1 K N O 1 2 4 6 OK, that looks like we might be able to balance it up on the RIGHT side now On the RIGHT we now need 1extra K, 1 extra N and 2 extra O Can you see how?

  20. Try 2KNO2 on the right: • 2KNO3 2 KNO2 + O2 2 K N O 2 6

  21. 2KNO3 2 KNO2 + O2 2 K N O 2 2 6

  22. 2KNO3 2 KNO2 + O2 2 K N O 2 2 2 6

  23. 2KNO3 2 KNO2 + O2 2 K N O 2 2 2 2 x 2 + 2 = 6 6

  24. 2KNO3 2KNO2 + O2 2 K N O 2 2 2 6 6 That is balanced!!!!!
