Hello Student,

From Water H2 preparation can mainly be done in two ways , which are as follows :-

By Action of Metals, Na, K , Mg , Zn ,Fe etc .

1. 2Na + 2H2O = 2NaOH + H2
2. Mg + H2O(Boiling Water) = MgO + H2

By Action of hydrides , NaH , CaH2 etc

1. CaH2 + 2H2O = Ca(OH)2 + 2H2

Hope this helps .

Hello Student,

The transition elements in ground state or stable oxidation state have (n-1)d^1-9 ns^1-2 electronic configuration.

Note Zn, Cd, Hg and Cn are not considered transition elements because in their ground state and stable oxidation state they do not have (n-1)d^1-9 configuration rather they have (n-1)d^10 configuration.

Hi Alok

Inorganic chemistry could be little bit of a problem. To study inorganic chemistry you can do the following :

Pick up NCERT book read it and mark the reactions. Go topic - wise . Make one chart for each compound of an element by seeing reaction from book. Start off with one compound . see the chart completely . now , on a blank paper , write out the complete chart without referring the original chart . If you can't try again.Practice them thoroughly.

You need to write reaction then only you can memorize well trust me it takes time but result will be fruitful.

All the best !!

Hope it helps :)
