    you right mate... H2 has two hydrogen atoms... number of atoms will be 2*moles... for hydrogen 2*.5... for neon 1*1... for CO2 it will be 3*.5..(as carbon has 3 atoms , 2 of oxygen 1 carbon)

    its far too easy than the one you have answered...:P num of atoms = moles * Avogadro constant... 1g of Hydrogen has 1 mole... same as neon... 20/20.... moles= m/Mr

    Earth revolves around its axis... (equator) so naturally a satellite following the earth's passage does not need any extra energy for rotation... and it always have some speed in the direction of its motion....

    haha... this is again not a perfect reason... increase in pressure favours the side where there are less number of moles..:) 3H2 + N2 ---> 2NH3... reactants have 3+1 = 4 moles while products have only 2 moles.... so reaction proceeds to the side with less no of reacting moles...

    yield increases with an increase in temp...??? so u think 400 is a greater temp than 500...????

    mate its is a mere application of Lechatlierz principal... HYber process is an exothermic one... so the graph will temp will show more production of NH3... and increase in pressure will also increase the production of NH3......
