What is Schrodinger equation for hydrogen atom?
A solution is prepared by dissolving 32.5 g of a nonvolatile solute in 200g of water.The vapor pressure above the solution is 21.85 torr and the vapou pressure of pure water bis 23.76 Torr at this temperature. What is the molecular weight of the solute
i want to ask that :-

we know that particle with opposite chage attract eachother......

ie + and - will attract eachother...

then why not the metals with + (positive charge) and non-metals with - (negative charge) attract eachother...............
The active mass of 7.0 g nitrogen in a 2.0 l container would be
Given that the spacing of the lines in the microwave spectrum of 24Al1H is constant at
12.604 cm1
. Calculate the moment of inertia and bond length of the molecule.
1. Equation VI-14a and VI-14b

(∆H│∆E)=-C(S)(T_1-T_0 ) 14a (∆H) and 14b (∆E)

Assume that the heat capacity of the calorimeter is much greater than the heat capacities of the product gases. Assuming C(S)=10.5 kJ/K determine the error in this assumption for the calculated energy of combustion of 1.0 g of benzoic acid using equation VI-12a and VI-12b

∆H= -C_p (C+D+S)( T_1-T_0 ) (12a)

∆E= -C_v (C+D+S)( T_1-T_0 ) (12b)

2. A student carries out the partial molar volume experiment using NaCl dissolved in water. His plot of ϕ vs. √m yield 2.9 as the slope and 16.3 as the y-intercept. Using a spreadsheet plot V1, V2, and V as a function of m for 0 ≤ m ≤ 3 molal. (b) At what value does V1= V2 ? (c) Give a physical interpretation for the behavior of V1, V2 and V as a function of m. (d) What is the change in total volume between 0 and 3 molal?
If S1 , S2 , S3 & S4 are the solubilities of AgCl in water , 0.01M CaCl2 , 0.01M NaCl & 0.5M AgNO3 solutions, respectively, then arrange S1 , S2 , S3 & S4 in increasing order. plz quick help?
H3PO3 is weak diprotic acid .What will be it's pH in its 0.2 M solution (Ka1=5×10-5,Ka2=10-13)
What will be (HS-) in a 0.1 M H2SO4 solution when 0.05M H2SO4 is added to it?(ka1 & ka2 are dissociated constant of H2S)
A Carnot engine operates using a heat source at 500°C, and a heat sink at room temperature (20°C). Suppose that as a heat source, you use the combustion of 100 cubic feet of natural gas at room temperature and pressure (e.g. in a fuel cell of some kind). Under ideal conditions, what is the largest amount of work that can be generated using this Carnot engine? Thank you! (Use the ideal gas law, PV=nRT, with the gas constant R=8.3 J/Kmol)
