i need some ideas for some working models related to chemistry.
for phsics : magent is a nice topic- by converting a metal into megnet by elecriticity
for chem. : 1)by showing volcanic erropsion by acid reactions
2) with a little skill in electronics u can create working models of different models of atoms
3)you can always display the neutralisation reaction
naoh +hcl ------> h2o + co2use concentrate materialsthen acid and base when mixed gives salt and waterthats the general idea
4)stucture of DNA (double helix)
who could imake this plz tell appratus
for making this modle
who could i mke water conductor is conductor of electricity plz tell appratusfor this
i need help in making a working model in chemistry in leval of class 10
i need some working models in chemistry for class 7th and need to do work on it in the class itself ..........
useless ideas very very useless
please tell me the appratus for making this model
i dont think thats it is for class 10
how we can make the model of volcano
how can we make a working model on electrochemical cell?????
