One mole of a gas obeys van der waals equation of state that is allowed to expand isothermally from v1 to v2. Compute ΔG for one mole of ammonia from 0.5 to 10 liters at 300k.
Explain why trans-1,2-difluoroethane is a non-polar molecule that while cis-1,2-difluoroethane is a polar molecule. Acrylonittrile has the formula CH2=CH-CN. Draw a line bond formla for acrylonitrile and label sigma bonds, pi bonds, which carbon at..
Rank the following in order of decreasing number of atoms
The standard molar enthalpy of formation of ClF3 is -405 kJ. 1/2 Cl2(g) + 3/2 F2(g) → ClF3(g)
The reaction of fluorine with ammonia produces dinitrogen tetrafluoride and hydrofluoric acid.F2(g) + NH3(g) -> N2F4(g) + HF(g)
Carbon dioxide is produced every time a person exhales. Some NASA spacecraft rely on this lithium hydroxide reaction to remove exhaled carbon dioxide from the air inside the spacecraft
What is the equilibrium concentration of hydronium ion in a solution that is 0.0877 M in HX and 0.240 M in X1- ion?
the total volume of hydrogen needed to fill the Hindenberg was 2.0x10^8 L at 1.00 atm and 25 C. How many kilojoules of energy were evolved when it burned?
A solution containing CaCl2 is mixed with a solution of Li2C2O4 to form a solution that is 3.5 x 10^-4 M in calcium ion and 2.33 x 10^-4 in oxalate ion. What will happen once these solutions are mixed. Ksp(CaC2O4) = 2.3 x 10^-9
The Phi ? and Psi ? angles of one alpha carbon located in the center of an alpha helix in myoglobin are -60o and -45o, respectively.
Compare and describe the 2 different definitions of acids and bases. Explain the difference between a weak acid and a stronge one
Silver consists of two major isotopes with the following percent abundances and atomic masses: 107Ag (51.84% and 106.90509 amu) and 109Ag (48.16% and 108.90476 amu). Calculate the average atomic mass of silver to five significant digits.
Starting with 3.00 moles of HBr in a 12.0 L reaction vessel, calculate the concentrations of H2, Br2, and HBr at equilibrium.
