Question #174723

Solid ammonium chloride undergoes sublimation on heating. In the vapour phase ammonium 

chloride decomposes to give NH3(g) and HCI(g). The following equilibrium is established. 

 NH4Cl(s) ⇌ NH3(g)+ HCl (g)

 What is the number of 

i) phases in the system, 

ii) components in the system, and 

 iii) degrees of freedom of the system?

i) Two phases, that is, solid and gaseous phases

ii) Three components (NH4Cl, NH3 and HCl)

iii) The system is disordered because gases are given out during the sublimation. (Gases move randomly, hence the molecules are very free)

The concentration of a solution of sodium hydroxide, NaOH, was determined by using it to titrate a known volume of a 0.250 M sulfuric acid (H2SO4) in accordance with the following equation: H2SO4(aq) + 2 NaOH(aq) --> Na2SO4(aq) + 2 H2O(l) If it required 46.57 mL of the NaOH solution to neutralize 25.00 mL of a 0.250 M H2SO4 solution, complete the following: The moles of H2SO4 consumed were The moles of NaOH reacted were The molarity of NaOH(aq) is
