The water vapour pressure at 293 k is 2338 pa and the vapour pressure of an aqueous solution is 2295.8 pa.determine it`s osmotic pressure at 313 k if the solution density at this temperature is 1010 kg/m3 . The molecular weight of the solution is 60.

Which of the following aqueous solutions remains neutral afterelectrolysis

In the reaction A + 2B ⇌ 2C, if 2 moles of A, 3 moles of B and 2 moles of C are placed in a 2 L flask andthe equilibrium concentration of C is 0.5 mol/L. The equilibrium constant (KC) for the reaction is.....and please tell how you know that the reaction is going forward .. imean how to calculate the reaction quotient ???
