A sample of ideal gas is in a sealed container. The pressure of the gas is 365 torr, and the temperature is 45, ^{\circ}C. If the temperature changes to 60\, ^{\circ}C with no change in volume or amount of gas, what is the new pressure, P_2, of the gas inside the container?
Supposed you have a beaker of water that is being heated on a hot plate. If you are studying the amount of heat that is requred to change the water temperature by a certin amount. What is a reasonable choice for the system and surroundings?
A critical reaction in the production of energy to do work or drive chemical reactions in biological systems is the hydrolysis of adenosine triphosphate, ATP, to adenosine diphosphate, ADP, as described by
Which of the following compounds have eclipsing hydrogens? If so do all the hydrogens eclipse each other? Are there any other eclipsing atoms?
If I have 7.0 moles of gas at a pressure of 0.10 atm and at a temperature of 50.1 degrees C in a balloon, what is the volume of the balloon? (Round to one decimal place.)
How much heat in kilojoules is evolved in converting 2.00 mol of steam at 150 to ice at -35.0? The heat capacity of steam is 1.84 and that of ice is 2.09 .
Using all the inorganic reactants neccessary and only CH3I and acetylene as carbon based compounds, make (2S,3R)-2,3-butanediol. Show both a retrosynthesis and forward synthesis.
Really struggling with this one dy/dt = 2t(y + 1) + 2at^3 where a is a parameter. Find the general solution of the ODE when a = 0 using the fact that it is separable. After this, use the fact that that it is a linear ODE to find an integrating fac..
A ten L Dewar containing liquid nitrogen tips over in your car while you are transporting it. If it completely vaporizes what volume of Nitrogen gas will be produced at 1 atm and 20 degrees C
Observe significant figure rules. Constants: ideal gas const = R = 0.08206 L atm/mole K; 1 mole of gas at STP occupies 22.41 L. Atomic masses: H 1.008 O 16.000 g/mole. You must show work to identify the limiting reagent; no credit for guessing.
the temperature derivative of the entropy at constant pressure is related to what important,measurable physical quantity? Can this quantity ever be negative?And also recall how the curvature of a surface is related to the sign of a certain derivat..
One of the most historically significant studies of chemical reaction rates was that by M. Bodenstein (Z. Physik. Chem. 29 (1899) 295) of the gas phase reaction and its reverse, with rate constants and , respectively. The measured rate constants a..
A solution was prepared from 10.0 mL of 0.100 M cacodylic acid and 10.0 mL of 0.080 0 M NaOH. To this mixture was added 1.00 mL of 1.27x10^-6 M morphine.
