18 gm glucose (C_(6)H_(12)O_6) is added to 178.2 gm water. The vapour pressure of water in
The enthalpy change for the reaction, C_(2)H_(6)(g)rarr2C(g)+6H(g) is X kJ. The bond energy of C-H bond is :
CuSO_(4).5H_(2)O(s)hArrCuSO_(4). 3H_(2)O(s)+2H_(2)O(g), K_(p)=4xx10^(-4)atm^(2) If the vapour pressure of water is 38 toor then percentage of relatative humidity is :(Assume all data at constant temperture)
19 gm of ice is converted into water at 0^(@)C and 1 atm. The entropies of H_(2)O(s) and H_(2)O(l) are 38.2 and 60 J//"mol " K respectively. The enthalpy change for this conversion is :
Vapour pressure of pure water at 298 k is 23.8 mm Hg. 50 g of urea (NH_2CONH_2) is dissolved in 850 g of water. Calculate the vapour pressure of water for this solution and it's relative lowering.
In the presence of excess of anhydrous ( in torr) of water taken up is governed by K_(p)=10^(12)atm^(-4) for the following reaction at 273K SrCl_(2).2H_(2)O(s)+4H_(2)O(g)hArrSrCl_(2).6H_(2)O(s) What is equilibrium vapour pressure ( in torr) of water in a closedvessel that contains SrCl_(2).2H_(2)O(s) ?
For an equilibrium H_(2)O(s)hArrH_(2)O(l), which of the following staytements is ture ?
For the reaction : C_(3)H_(8)(g) + 5O_(2) (g) to 3 CO_(2) (g) + 4H_(2) O (l) at constant temperature Delta H - Delta U
A simple of thliqid H_(2)O at 18.0 g is inlected into an evacuated 7.6 L flask maintained at 27.0^(@)C . If vapour pressure of H_(0)O at 27.0^(@)C is 24.63 mm Hg, what wight of the water will be vaproueied when the ssystem comes to equilibrium? Assume water vapours behaves as an ideal gas. The volume occupied by the liquid water is negligible compared to the volume of the container:
