BALANCING EQUATIONS NO2 - Balancing equations made easy

Here is an equation that needs to be balanced: KNO 2 + O 2 KNO 3 Step 1: list all the elements neatly under the arrow KNOKNO

Here is an equation that needs to be balanced: KNO 2 + O 2 KNO 3 KNOKNO Now add up how many K N and O you have on each side

Here is an equation that needs to be balanced: KNO 2 + O 2 KNO 3 KNOKNO Now add up how many K N and O you have on each side 1

Here is an equation that needs to be balanced: KNO 2 + O 2 KNO 3 KNOKNO Now add up how many K N and O you have on each side 11

Here is an equation that needs to be balanced: KNO 2 + O 2 KNO 3 KNOKNO Now add up how many K N and O you have on each side 11

Here is an equation that needs to be balanced: KNO 2 + O 2 KNO3KNO3 KNOKNO Now add up how many K N and O you have on each side 11 1

Here is an equation that needs to be balanced: KNO 2 + O 2 KNO3KNO3 KNOKNO Now add up how many K N and O you have on each side 11 11

Here is an equation that needs to be balanced: KNO 2 + O 2 KNO 3 KNOKNO Now add up how many K N and O you have on each side 11 11

Here is an equation that needs to be balanced: KNO 2 + O 2 KNO 3 KNOKNO Now add up how many K N and O you have on each side

Here is an equation that needs to be balanced: KNO 2 + O 2 KNO 3 KNOKNO Now add up how many K N and O you have on each side = 4

Here is an equation that needs to be balanced: KNO 2 + O 2 KNO 3 KNOKNO K and N are fine BUT O is not balanced

Here is an equation that needs to be balanced: KNO 2 + O 2 KNO 3 KNOKNO We need more O on the left hand side We only want 1 more O BUT we can only have 1KNO 3, or 2KNO 3 or 3KNO 3

Here is an equation that needs to be balanced: KNO 2 + O 2 KNO 3 KNOKNO Lets see what happens if we have 2 KNO 3 on the left

Here is an equation that needs to be balanced: KNO 2 + O 2 2KNO 3 KNOKNO Lets see what happens if we have 2 KNO 3 on the left

Here is an equation that needs to be balanced: KNO 2 + O 2 2KNO 3 KNOKNO Lets see what happens if we have 2 KNO 3 on the left 2

Here is an equation that needs to be balanced: KNO 2 + O 2 2KNO32KNO3 KNOKNO Lets see what happens if we have 2 KNO 3 on the left 2 2

Here is an equation that needs to be balanced: KNO 2 + O 2 2KNO 3 KNOKNO Lets see what happens if we have 2 KNO 3 on the left x 3 = 6

Here is an equation that needs to be balanced: KNO 2 + O 2 2KNO 3 KNOKNO Lets see what happens if we have 2 KNO 3 on the left OK, that looks like we might be able to balance it up on the RIGHT side now On the RIGHT we now need 1 extra K, 1 extra N and 2 extra O Can you see how?

Try 2 KNO2 on the right: KNO 2 + O 2 2KNO 3 KNOKNO

KNO 2 + O 2 2KNO 3 KNOKNO

KNO 2 + O 2 2KNO 3 KNOKNO

KNO 2 + O 2 2KNO 3 KNOKNO x = 6

2KNO 2 + O 2 2KNO 3 KNOKNO That is balanced!!!!!
