Question 1 - Write down the wave function for BMO for a heteronuclear diatomic molecule AB assuming that the electron on an average spends 90% of its time on nucleus A and 10% of its time on nucleus B.
Question 2 - State the Carnot's theorem and deduce the expression for efficiency of ideal heat engine.
a 25ml portion of an unknown monoprotic acid solution was titrated with 1.5 m naoh. it was found 20ml of this base was
Hemoglobin has a positive charge of +5 and a radius of 3.55 nm in water. How far will the protein travel in one hour in an electrophoresis gel at 25C when a field
Explain the possible effect of your results of the following experimetnal error or variations (a) the reaction flask you used in the kinetic runs was rinsed with water and not dried
the radioactive isotope carbon-14 is used for radiocarbon dating. The half-life of carbon-14 is 5730 years. A wooden artifact in a museum has a 14C count that is 0.125 times that found in living organisms. Estimate the age of the artifact.
calculate the velocity and the degree of inhibition of an enzyme catalyzed reaction in the presence of 6x10-4 M substrate (KM = 10-3 M) and 2.5x10-4 M of a non-competitive inhibitor (Ki = 3x10-5). Vmax = 515 nmoles/L/min.
To what volume should you dilute 45mL of a 12M stock HNO3 solution to obtain a 0.121M HNO3 solution
Without consulting entropy tables, predict the sign of Delta S for the following process and choose the correct reasoning for your prediction: N2(g, 10 atm) ----> N2(g, 1 atm). The mass of N2 remains constant.
The lethal inhalation dose of sarin for a 200 pound person has been determined to be 0.0015 mg. Determine the LD50 of sarin that researchers used to calculate this lethal inhalation dose.

An unknown compound B has the melting point 112.5-114 degrees C. It is suspected that B is either X or A, each compound having reported mps of 115degreesC. Assuming B is X, indicate the mp range (give actual values) for the Melting points
Methanol is a probable replacement for gasoline. The entire combustion of methanol forms carbon dioxide and water. CH3OH+O2--->CO2+H2O
Question- 1.) If your Aspirin sample did not dry completely and contained water in the sample would it require more or less NaOH solution to reach the endpoint of the titration?
