the diffusion coefficient for nitrogen in the metal at 1150 C is 1x10^-11 m^2/s and the end is 3.5 kg/m^3, what is the nitrogen concentration at a position 2mm into the sheet away from higher concentration end?
Ammonium Hydrogen sulfide decomposes on heating, NH4HS(s) NH3 (g)+H2S(g). If Kp for this reaction is .11 at 25 degrees celcius (where partial pressures are measured in atmospheres), what is the total pressure in the flask at equilibrium
A student mixed 75.0 mL of water containing 0.75 mol HCl at 25 degrees C with 75.0 mL of water containing 0.75mo of NaOH at 25 degrees in a foam up calorimeter. The temperature of the resulting solution increased to 35 degrees C.
