Show that the coefficient of performance of a reversed Brayton ASC heat pump can be written as
COPreversed Brayton ASC HP= ((CR)k-1)/(CR)k-1-1where CR is the compression ratio of the system.
write out the mechanism for alcoholysis of acetyl chloride with isopropyl alcohol. will steric factors slow this reaction down in a way
Draw a phase diagram labeling all the above points. Also label the melting point curve, the boiling point curve, and the solid, liquid, and gas regions.
Calculate the molality of a solution prepared by dissolving 112. grams of copper (II) sulfate in 450. mL of water at 25 oC
If the Rate constant in SI Units for NO formation is 1.8x10^8 exp(-38,370/T) as well as the reaction rate at 1870 Celsius and 2 atm can be approximated as 2k[N2][O] with the mole fractions of N2 as well as O being approximately 74% and .15%,
Question- What is the density (in g/cm3) of a fictitious elemental solid which packs in a body-centered cubic unit cell with an atomic radius of 144 pm and a molar mass of 157 g/mol?
Explain what is the heat released during reaction. Also what is the enthalpy of neutralization. Does doubling the volumes of acid and base double the amount of heat. Does doubling the concentration of acid base double the amount of heat released
a tire has a volume of 535 cm3 at a temprature of 20 c while in use the temprature of the tire rises to 65 c calculate
a box contains 126000 red marbles and 885000 yelllow marbles. What sample size is required to reduce the sampling standard deviation of red marbles to 1.85%
Why is it that hex-1-ene, (Z)-hex-2-ene, and (E)-hex-2-ene are considered to have a high boiling point?
A first order reaction has a half life of 26.4 sec. How long will it take for the concentration of the reactant to fall to 1/8 of its original value
If you have 300.0 mL of water at 25.00 degrees C and add 130.00 mL of water at 95.00 degrees C, what is the final temperature of the mixture? Use 1.00 g/mL as the density of water.
In the reaction between butanal and propanal, two different aldehydes are used and thus four different aldol addition products can be formed (which makes this an undesirable route for making aldols). Depict the skeletal structure of the aldol addi..
