One mole of an ideal gas at 300 K in thermal contact with surroundings expand iso-thermally from 1.0L to 2.0 L against a constant pressure of 3.0 atm. In this process, the change in entropy of the surroundings (delta S surr) in J/K is.
What is the purpose of washing your cyclohexene with saturated sodium bicarbonate. Why do you think it is more practical to wash with a solution instead of adding solid sodium bicarbonate to your cyclohexene
show the total ionic and net ionic forms of the following equation. make sure the equation is balanced before proceeding. Fe(s) + CuSO4(aq)
what is the structure of an ester of 2-methylpropionic acid that has the molecular formula: C8H13ClO2 and 5 signals in its 1H NMR spectrum?
The increase in volume is due to the H2 gas created. 50 g of tin (Sn) is 0.421 moles. That is also the number of moles of H2 that are created. Use tha ideal gas law to compute the added volume due to that gas.
probability that you removed 8 straight nails and 2 bent nails? To find the probability, first derive a general expression using the following notation
A blight has wiped out the pineapple crop. You are asked to synthesize the ester that is responsible for the scent of pineapple, butyl butanoate. Draw the skeletal structure of the reagents needed to make this scent.
Sketch TS diagrams for the following four ideal gas cycles: Otto; Diesel; a rectangle on a PV diagram; and a "right triangle" on a PV diagram in which the base is an isobaric, the altitude is an isochoric, and the "hypotenuse" is an adiabatic.
