Balancing chemical equations help.
« on: August 15, 2013, 11:03:12 PM »
Hello guys,

I was wondering if anyone had some tips/techniques/rules to balancing chemical equations that would help me balance faster and more efficiently.

All help is appreciated.

Thank you.

This really works better, if you give us some examples.  Show us one that you can do, and show us one that you can't.  "Teach me everything" posts, on any topic, just simply don't work on a forum dialog.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

I can do almost any, but it takes so long for me. I need a strategy.

Hi,
Prior knowledge on writing correct chemical formula is essential. A little arithmatic on balancing each element will  be an added advantage

The mass of the products = the mass of the reactants.

Always know the Left hand side and Right hand side must have the same amount of atoms for each element.

e.g; SnO2 + H2  :rarrow: Sn + H2O - From this, you can see that on the Right hand side there is only 1 atom of Oxygen, while on the Left hand side, there are 2. Put a co-efficient of 2 in front of H2O.

SnO2 + H2 :rarrow: Sn + 2H2O

Although we have balanced the Oxygen, we have unbalanced the Hydrogen and must balance that next.

All there is left to do is balance the Hydrogen, to do this, simply place a co-efficient of 2 on the Left hand side in front of Hydrogen.

SnO2 + 2H2 :rarrow: Sn + 2H2O

Our final equation consists of:
1 Tin
2 Oxygen
4 Hydrogen
On either side

Hopefully this can help you wrap your head around the whole idea of balancing Chemical Equations.
If there are any specifics that you need help with, please post them.

Are you answering the question that was asked, or the question that you think you know the answer to? OP stated he KNOWS how to balance equations, he just looks for a more efficient approach.

I realized while I was writing it out that it didn't specifically answer his question for tips, but I thought a little revision would never hurt, I apologize if this was no help to OP.

No it's fine, that is somewhat helpful to me.
