Where did the energy required to maintain the system at a constant temperature in the two isothermal processes described?
PAth A- sudden irreversible decrease in pressure from P1 to P2 ( P2<P1)
Path B- Gradual reversible derease in pressure from P1 to P2 such that the internal and external pressures remain in equilibrium at every step along the path. and how is the energy related to the amount of work that was perfromed along each path?
The values of delta h and delta s for the reaction CaCo3(s) yields CaO(s)+CO2(g) are 177.8kJ and 160.5 J/K respectively. the pressure of CO2 at equilibrium for the process
While Xeloda works well, it is effective for colorectal tumors and liver cancer. What are the drawbacks for extending this therapy to other types of cancer?
Two vessels are labeled A and B. Vessel A contains NH3 gas at 70°C, and vessel B contains Xe gas at the same temperature. If the average kinetic energy of NH3 is 7.1 10-21 J/molecule, calculate the mean-square speed of Xe atoms in m2/s2.
the equilibrium partial pressure for the reaction 2NO2(g)--> N2O4(g) are 0.0686 atm for NO2(g) and 1.250 atm for N2O4(g).
the structure they gave me already has two nonbonding electrons on Bromine with no formal charge
Draw those that have a trisubstituted ring where the methyl groups are oriented meta.

Assume the total heat capacity of the air C air=30 J/K. Describe what's the likely ice will ne after the system reaches equilibrium. b) Estimate theliekly final temperature after reaching equilibrium
Calculate the pH of a buffer solution (consisting of 30mL 1.0M NaA + 30mL 1.0M HA and a pH of 4.75) mixed with 2mL of 1.0M NaOH. (In class we got a calculated pH of 4.63 for the mixture of the buffer solution with 2mL 1.
