do post such articles on other topic too

yeah read wrong its just above centre , won;t be 0

2] base area * E

= pier^2E

i think for the first 1 it would be 0 , logic i think is same as that we use for a cube with charge at one of the corner ,and those prob we take the flux to be 0 for the three sides at which the charge is located

like lord ganesha i love to study , studies is my passion my ultimate aim , my time pass , my entertainment...........

and like the lord i want to gain knowledge about every small thing in the universe

more then 50k goiitians and hardly any replies

is @ the angle of inclination

com on guuuys more replies

2 to 3 hrs on sunday i think should be enough

thanks nics more responses needed

please give this link to other also

let me start
physics - mechanics only fluid left i.e till elasticity
optics ,modern physics - nothing
thermal physics - entire
electricity - till capacitors
magnetism -nothing

organic - goc ,hydrocarbons ,aromatic compd
phy chem - soln ,ionic,chem eq ,gaslaw , chem bonding stoichio

maths
entire trigo
algebra almost
calculas -started
vector & geometry -nothing

hello to all jee 09 aspirants , i thought that i should know that where am i standing with respect to others ,so i request all the freshers to post the topics they have covered till now

PHYSICAL

stoichiometry , ionic - chem eq , solns , electro chem

stoi , and chem eq these are easist they require simple mole concept based on the reactions , for reactions u should go for strong knowledge of periodicity

organic me to sirf 2 he chapter kiye hai kaise maddat karo inorganic to sirf code banakar ratlo

hope i was able to relieve someone a bit

total no of moles = 8

40% = 3.2 moles of the mixture

now this 3.2 moles of mixture contain 0.8 mole of N2 rest H

N2 + 3H2 = 2NH3

now 1 mole ofN2 reacts with 3 mole of H2 therefore 0.8 mole of N2 will react with 2.4 mole of H2 which is present

therefore from the reaction 1mole N2 = 2 mole of NH3

0.8 mole of N2 = 1.6 mole of NH3
