the value of delta H for 2CO(g) + O2 (g) = 2CO2(g) is -482 kJ. Calculate the heat released to the surroundings when 38.5 g of O2 (g) reacts with excess CO
the equilibrium constant is 1.5x 10^-2 at 370 degrees C and delta H is 16.0 KJ at 25 degrees C. Assuming delta H and delta S are temperature independent, calculate delta S for the reaction
process it is given that Rubidium has a heat of vaporization =69.0 kJ/mol at its boiling pt= (686°C). Compute ΔS for this process?
The use of phenols such as tert-butylcatechol as free-radical scavengers is based on the fact that phenolic hydrogens are readily abstracted by radicals
It is 2734 mi between Phoenix, Arizona, and Philidelphia, Pennsylvania. What is this distance in km?
For each reaction between a ketone and an amine, draw the curved arrow(s) to show the first step of the mechanism, then draw the final organic product
use the measure "mass of 10.00mL" which is 10.574g, to calculate the density of mass NaCl which is 5.923g
The major reason that antiparallel beta-stranded protein structures are more stable than parallel beta-stranded structures is that
The aqueous electrolytic solution (d= 1.230 g/cm^3) in a typical automotive battery contains approximately 368 g of hydrogen sulfate (H2SO4, sulfuric acid, MM= 98.07948 g/mol) per liter. Calculate the following concentrations
Use Coulomb's law to calculate the ionization energy in kJ/mol of an atom composed of a proton and an electron separated by 150.00 pm.
What is the volume in mL of 0.664 M HCl(aq) needed to neutralize the hydroxide ions present in 32.2 mL of 0.851 M NaOH(aq).
How much heat is required to convert 25.0g of ethanol at 25 degrees C to the vapor phase at 78 degrees C?
Nitrate ion (NO2)^(-1) can be analyzed by creating an acidic solution of nitrite ion and adding excess iodide (I)^(-1) ions creating NO and I2. The I2 combines with excess (I)^(-1) to create (I3)^(-1).
