  • Ohhh!  Hope I don't forget that.
  • S8     +   O2    -->      S  O2
  • S   =   8 O   =   2
  • ___________________
  • | | |
  • S   =   1 O   =   2
  • And don't forget that if there is no number after an element, it is assumed it will be 1
  • The second step is a major rule when balancing equations which is that-- We can only change the coefficients (which are the numbers in from one the atoms) While the numbers after the atoms (subscripts) cannot be changed.
  • S8 +      O2    -->      S O2
  • COEFFICENTS
  • SUBSCRIPTS
  • But for S (sulfur) it's two different subscripts. To fix this we can change the coefficient of the S on the right side and make it into an 8 which means-- 
  • STEP #2 : Changing the Coefficient.  
  •  S8     +   O2    -->      SO2
  • S   =   8 O   =   2
  • ___________________
  • | | |
  • S   =   1 O   =   2
  • So if there is no coefficient in front of the element, assume its 1. So as you see there are two O (oxygen) on both sides of the equation-- which is fine.
  • S   =   8 O   =   2
  •  S8     +   O2    -->      S1O2
  • ________________________

  • S   =   1 O   =   2
  • 8
  • x  8  =  16
  • x  8  =  8
  • 8 times the 1 sulfur equals 8. Now both sides have 8 S, but the 8 would also mean that we have to multiply it with the 2 of oxygens which then gives us unbalanced oxygens.--
  • S   =   8 O   =   2
  • With this, we can change the Coefficient on the left side to 8...  As 8 times 2 would equal 16 Giving us the same amount for both sides for Oxygen and Sulfur... Moving on to step 3!
  •  S8   +      O2    -->      S1O2
  • Okay let me just write that down...
  • x  8  =  16
  • 8
  • ________________________
  • | | |
  • S   =   1 O   =   2
  • 8
  • x  8  =  8
  • x  8  =  16
  • STEP #3 : ONLY CHANGE the Coefficients
  • Now that part is easy -squezy!
  • We then move on to ONLY CHANGING the coefficients... Not subscripts.
  • S8  +      O2    -->      SO2
  • S8  +      O2    -->      SO2
  • 8
  • 8
