Sodium carbonate was used to precipitate silver from a solution. 6.00 grams of silver carbonate were recovered from 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 8.1x10-12. Assume water has a density of 1.00g/mL.
Calculate the theoretical yield of C2H5Cl when 106 g of C2H6 reacts with 236 g of Cl2 assuming that C2H6 and Cl2 react only to form C2H5Cl and HCl
20.00mL of radiator liquid, ethylene glycol has a mass of 20.85 g. What is the density of the liquid?
A pure fluid is described by the following expression for Gibbs free energy: G = gamma(T) + RTlnP, where gamma(T) is a substance specific function of temperature.
