Sodium carbonate was used to precipitate silver from a solution. 6.00 grams of silver carbonate were recovered 1.500L of solution. What was the concentration in ppm of silver ions in the original solution? You may ignore ionic strength and coupled equilibria. The Ksp for silver carbonate is 8.1*10^-12. Assume water has a density of 1.00g/ml.
Chemical Kinetics - Determine the time taken by a reactant to reach a particular concentration
A chemical reaction releases 58,500 J of heat into 150 g of water. Assuming no heat is lost to the surroundings
Calculate q,w,delta U and Delta H for each segment and for the cycle in which the direction of each process is reversed. In the graph all it says is the P initial =16.6 bar and Vinitial=1.00L and P final=16.6 bar and V final =25L
A gas is compressed from initial volume of 5.60L to 1.23L by an external pressure of 1.00atm. During the compression the gas releases 128J of hear. What is the internal energy of the gas?

Sodium atoms emit light with a wavelength of 330 nm when an electron moves from a 4 p orbital to a 3 s orbital. What is the energy difference between the orbitals in kilojoules per mole?
Organic Chem: A hexose A was obtained after (-) glyceraldehyde underwent three successive Killani-Fischer syntheses. Oxidation of A with nitric acid forms an optically inactive aldaric acid B. Wohl degradation of A followed by nitric oxidation giv..
A gas expands and does P-V work on the surroundings equal to 321 J. At the same time, it absorbs 177 J of heat from the surroundings. Calculate the change in energy of the gas.
This solution was back-titrated with a 0.0440 M Ga3 solution until all the EDTA reacted, requiring 12.0 mL of the Ga3 solution. What was the original concentration of the V3 solution?
What is the total volume of gaseous products formed when 198 liters of propane (C3H8) react completely according to the following reaction? (All gases are at the same temperature and pressure.) propane (C3H8) (g) + oxygen (g) --> carbon dioxide (g..
What potential issues might arise if the pH of your buffer is too close to the pI of your protein of interest? Why might an extreme buffer pH ( 9) be unsuitable?
The Bracket series of emission lines falls in the infrared region of the em spectrum, and each line is a result of an electron falling from a higher Bohr orbit to the n=4 level.
