A mixture of 0. 10 mol of NO, 0. 050 mol of H2, and 0. 10 mol of H2O is placed in a 1. 0-L vessel at 300 K. The following equilibrium is established: At equilibrium (a) Calculate the equilibrium concentrations of H2, N2, and H2O. (b) Calculate Kc.

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

What is the molarity of the solution produced when 145 g of nacl is dissolved in sufficient water to prepare 2.75 l of solution?

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
