Balancing Equations?

Showing 1 to 7 of 7

I am absolutely clueless on how to balance equations in chemisty, please can somebody help! - exam on the 25th May and desperately need help with all Biology,Chemistry and Physics topics!

Right, my friend does this:

1. Add up how many there are of each element

e.g. H2O

H=2  O=1 etc.

2. Find out how to balance the equation so there are the same amount of each on both sides.

(usually you just put a 2 infront of some of the elements / compounds

Hope this helps :)

Say you have the equation

N2 + O2 --> NO

1). add up how many of each element you have on either side of the equation.

In this example, you have 2 nitrogens and 2 oxygens on the left hand side and 1 nitrogen and 1 oxygen on the right hand side.

2) to balance the equation there must be the same amount of each element on both sides of the equation.

In this example, to balance the equation you would need to write a 2 in front of the NO as this would give 2 nitrogens and 2 oxygens on both sides.

Therefore, the balanced equation would be

N2 + O2 --> 2NO

I hope this helps, if you visit my profile/page thing I will upload some examples for you to try :)

hey, my friend has trouble with balancing equations too, but i tell her just to make sure in the end you have the same number of atoms on both sides, similar to what Emma and Alice have said.

But there isn't much you can do except keep practicing until you get it, and ask your teacher for some questions to see if that helps, or even ask he/she to sit with you and try some out. this is one of the things were some people will find dead easy whilst others will find hard so don't worry, your not the only one. and same here, my chemistry exam is on the 25th may :D **

Hey, it's me again. Here are some questions for you to practise balancing with.

I hope this helps :)

This is an amazing link from Youtube: http://www.youtube.com/watch?v=RnGu3xO2h74

This shows the exact step of balancing equations. This is the link that helped me understand the concept of balancing equations!

just be logical and you will eventually get the answer
