At a fixed temperature, equal moles of N2 (g) and H2 (g) are mixed in a constant pressure container (the volume of the container changes in order to keep the pressure at a constant value). The N2 (g) and H2 (g) are allowed to react, producing NH3 (g):
N2 (g) + 3 H2 (g) → 2 NH3 (g) If the initial volume of the container, before any reaction takes place, is 5.70 L, determine the volume of the container after the N2 (g) and H2 (g) have reacted to completion.
What is the pH of the sodium phosphate buffer described in problem if 1 ml of 10M NaOH is added? What is the pH of 1 liter of water if 1ml of NaOH is added?
Use this information to compare how long it will take to obtain molecular scale mixing of such a gas over i) distance 1*10^-4 m and ii) 10m
Phosphorous trichloride (PCl3) is produced from the reaction of white phosphorous (P4) and chlorine: P4(s) + 6 Cl2(g) → 4 PCl3(g) . A sample of PCl3 of mass 298 g was collected from the reaction of 75.37 g of P4 with excess chlorine.
