balancing equcations

[Maqboole]

hi can some one help me in balancing equcations? i would be thankful

[iNow]

Specifics? Any?

[insane_alien]

the number of atoms of a specific element on each side must be equal. when this is true of all elements involved then it is balanced. it is as simple as that.

There is no specific method to do that really. Just try to add all the atoms of individual elements from each sides and balance it such that both sides would have same number of atoms of each individual elements. I can't however stress enough to practice and practice as much as you possibly can unless you feel confident to balance any equations!

Some issues with connectivity...

 

The oxidation states must also make sense. For example, Calcium hydroxide is given as Ca(OH)2 because calcium has two electron holes (2+) in its outermost shell and the OH "radical" has one electron to share (1-). This is due to the fact the O is 2- and (in this case, look up hydride anion) H is 1+; the sum nets a 1- charge. These must balence as well which is why there are 2 OH to each Ca.

 

These charges are given on the periodic table, e.g. alkali metals 1+, alkaline earths 2+, etc. This gets somewhat sketchy toward the right of the table where empty shells> (see B, see also hypervalency) can exist.

 

So, simply balencing the number of each atom on each side of the arrow is not all you have to do. This will require memorization or better, a thorough understanding of the Periodic table.

 

Learn it, live it, love it, and your there.

 

Cheers,
