The liquid-phase reaction A + B → C follows and elementary rate law and is carried out isothermally in a flow system. The concentrations of A and B entering the reactor are 1 M. The
volumetric flow rate of the inlet stream is 10 dm3

/min. Two reactors are available. One is a gray
200 dm3 CSTR that can be heated to 77 °C or cooled to 0 °C. The other is a white 800 dm3 PFR
operated at 300 K that cannot be heated or cooled but can be painted red or black. Given: k =
0.07 dm3
/mol. min at 300 K and Ea = 20 kcal/mol.

Which statement explains why the bonds between non metals tend to be covalent? the bonds are found to be nondirectional they have large differences in electronegativity they have small differences in electronegativity they have ions that produce an electrostatic pull

What is the molar mass of the anhydrous compound? answer using four significant figures. 36.02 g/mol 120.15 g/mol 156.12 g/mol

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 .
