We had Science last lesson and we're doing Chem atm. We're learning how to balance scientific equations. Which, of course, just confused my tiny brain cells further than they were already confused.
SO I decided to look it up on *drum roll* GOOGLE.
And anyway, I found this.
Take a look at the unbalanced equation SnO2 + H2 → Sn + H2O
atoms on the left hand side of the equation and only one on the right hand side. Correct this by putting a coefficient of 2 in front of water:
SnO2 + H2 → Sn + 2 H2O
This puts the hydrogen atoms out of balance. Now there are two hydrogen atoms on the left and four hydrogen atoms on the right. To get four hydrogen atoms on the right, add a coefficient of 2 for the hydrogen gas. Remember, coefficients are multipliers, so if we write 2 H2O it denotes 2x2=4 hydrogen atoms and 2x1=2 oxygen atoms.
SnO2 + 2 H2 → Sn + 2 H2O
The equation is now balanced.
Yes I did just copy and paste that off Google but I understand. Kind of.
And yes it is an American site but it explains the equations pretty much like how my Science teacher was trying to explain it to me. I hope that when I walk into Science tomorrow, it'll be like a sudden light being turned on; like ill just all-of-a-sudden understand.
Wishful Thinking.
