A list of chemical equation balance software

A list of chemical equation balance software

Hello, my friends.

I'm a editor at a educational press. Recently we are compile a test
book
for high school students. The job of me is to write many chemical
equations for students to practice. Also I must give the key to them.

In fact, as a bachelor of chemistry, I have no problem to balance any
chemical equations, but balancing so many equations is really a
tedious
work!! So I think I need a software to do this.

After searching on the internet I found these.

1. http://www.webqc.orgbalance.php
A online chemical equation balancer, but a web-based UI interface cost
me lots of time. Also I always make mistakes when typing in the
equation. The editor is not user friendly.

2.http://www.nandoy.combalance
This is also web-based, also it need buy to be it's member.The editor
is
not user friendly.

3. www.intellibalancer.com
This shareware program is quite powerful because it format my equation
automaticly during typing. The balance is also very fast. It even can
export chemical equations to HTML.

But I'm not from the USA.It's always takes lots of time to purchase a
program from other country. So a pity a can't choose this software.

Seems a chemical software too, but I don't know what a software it is.
Just the price $99 makes me frightened )

5.http://www.gold-software.comChemicalEquationExpert-review14801.htm
this software is called Chemical equation Expert, it do can balance
chemical equations. But it has many weakness, first, for equation that
has more than 8 compound, it becomes very very slow, the maxim number
of
compounds it support is 16, I think it's too few.

For now I download a 7-day trail version of http://www.intellibalancer.com
, because all my equation will of
cause be balanced in 7 days )

However, I think for a chemist, a good equation balance software is a
must have tool, so I'm always waiting for a freeware. If you know any,
please reply this message.
