Hello,

Together with a friend, we wrote an application on mobile phones for middle school students, it's field is inorganic chemistry.
We would like to ask for both substantive comments and overall assessment of the application

DESCRIPTION :

Chemist will help you in chemical tasks!
You do not have to know everything by heart! Chemist application will be enough!
Use the Periodic Table just like a computer keyboard.
The chemist will show you possible products and balance the chemical reaction! All you have to do is enter the reactants.
With the Chemist you will learn everything you need to know about the elements, compounds and chemical reactions.

Details :

Chemist contains names, designs, and many other options for more than 1,500 chemical compounds.
Chemist shows the reaction products of over 2,000 chemical reactions and balances them immediately .
Chemist balances all redox reactions .
Chemist includes lots of information about compounds, the elements and chemical reactions.

Exemplary compounds :
 - Oxygen acids : HNO₃ , H₂SO₄ , H₃PO₄,H₂CO₃
 - Anaerobic acids : HCl , HBr , H₂S
 - Hydroxides : NaOH , Ca(OH)<sub]2[/sub] Mg(OH)₂ , Al(OH)₃
 - Acidic oxides : SO₃ , Cl₂O₇ , N₂O₅
