Homework Statement How much dcm3NH3would we get if 2 mole of N2 react with the same amount of H2 Homework Equations I tried this n=V/Vm then get V=n x Vm then get 2 mole x 22.41 dm3 x mole -1then get 44.82 dcm3 but i don't now if it is right so any help would be great The Attempt...

Thanks very much sir astronuc

No i don't now how if you could post it how to do also the derivate then it would be ok and thanks for this post

Homework Statement the parametric equations of the motion are x=(t)^2m and y=(6t-1.5t^2)m i need to find the velocity at the time moment of t=2s Homework Equations The Attempt at a Solution so this are the four solutions v=o,v=2m/s,v=4m/s,6m/s .

as an chemical engineer you don't need such an advance math so better focus in your chemistry

also there in chemistry ther is a method to creat exp: metal to gold due to bombing the atoms and creat new atoms
