When I get stuck on balancing equations does anyone have any tips?

There's a similar post already under "How to balance"

A technique for more complex equations. Balance compounds that appear once. Often, it is required to use fractions and then multiply the entire equation by the denominator of the function to cancel out the fraction

In addition, these tips might also help:

1. Start by counting and making note of all of the elements present on each side of the equation.

2. Count the number of molecules of each element on both sides of the equation before starting to balance them.

3. Look for atoms that make up a group or family (e.g sulphate, phosphate or ammonium). These will go throughout the chemical reaction the same. Treat them as an indivisible team. They should be balanced as a whole unit.

What I usually do is pick an element that I can easily balance on each side. Then, I draw an arrow under the element with the number of moles of each element, and often check each one to make sure there is the same amount on each side. Another tip is to always do Oxygen (if it is in the equation) last!

I like to write out the amount of each element on each side of the equation to avoid simple memory mistakes. This is also helpful when balancing the equation itself because you can constantly refer back to it and make sure you are making correct calculations.

For me the best way to balance equations is writing each element on the side and counting it. Take one step at a time looking at the one which looks the simplest.
To make sure that the equations balanced I just count each element again to reassure.

I like to record out the amount for each element on each side, it makes it more clear to me and helps with memory. It is a good way to refer back to proper numbers and assure you're on the right track for calculations.

I usually balance the atoms that are solo last because it makes it a little simpler. For example, in combustion reactions, it's usually easiest to balance every other atom before the oxygen molecules because they're alone so you don't have to keep changing all the numbers.

A trick I tend to do somewhere on the side of my paper for extra help is creating a t-chart & tallying the amount of moles of each element I have for each side. It's a nice, visual way to make sure you're balanced!
