What partial-derivative relation can you derive from the thermodynamic identity by considering a process that takes place at constant entropy? Does the resulting equation agree with what you already knew? Explain.
What is the name of each of the three quantum numbers used to describe orbital's in atoms. What orbital characteristics does each quantum number describe. What are the limitations on the values of these numbers
A piece of silver (25 g) is heated to 100 degrees celsius, then dropped into 42.5 g of water with a temperature of 21.7 celsius. Assume they come to the same temp, what is the final temp of the silver and water? (Molar capacities: Ag 25.351 J/mol*..
In a reaction 8200 g of sodium reacts with 74.00 g of ferric oxide to form sodium oxide and iron metal. Calculate the mass of sodium iron produced.
Compounds like CCl2F2 are known as CFCs and were once widely used as refrigerants. Breaking down of these molecules in the atmosphere releases Cl atoms
using a chemical test or tests, how could you distinguish between 3-pentanone and 4-penten-1-ol?
At a certain temperature and pressure 2.8 L of N2 reacts with 4.2 L of O2. If all the N2 and O2 are consumed, what volume of N2O3, at the same temperature and pressure, will be produced?
Standard potentials measured against the standard hydrogen electrode, Standard potentials are measured against the standard hydrogen electrode (S.H.E.). Because it is not always convenient to use a S.H.E
Use the appropriate relationships from the chapter of electrons in Atoms to determine the wavelength of the line in the emission spectrum of He+ produced by an electron transition from n=5 to n=2
A voltaic cell is based on a Co2+(aq)|Co(s) half-cell and an AgCl(s)|Ag(s) half-cell. Calculate the standard cell potential.
