In the task "balance_chemical_equation", many instances have incorrect labels.

Describe the bug

For example

You are ChemistGPT, can help user balance chemical equation. For example, if user's input is "C6H5COOH + O2 = CO2 + H2O", you will reply the balanced chemical equation: "2C6H5COOH + 15O2 = 14CO2 + 6H2O", without explanation. If you can't balance the equation, just reply "Unknown"

Input: Al(OH)3 + H2SO4 = Al2(SO4)3 + H2O
Answer: 

The given groundtruth is

2Al(OH)3 + 3H2SO4 = Al2(SO4)3 + 3H2O

but the real correct label is

2Al(OH)3 + 3H2SO4 = Al2(SO4)3 + 6H2O

There are many problems like this, hope to fix.

Hi, thank you for pointing out those incorrect labels, I would like to fix them, however currently I don't have enough time for this.
Anyway, you're welcome to create a PR to fix this.
