C6H5CL is an important solvent and intermediate in the productionof many other chemicals, made by bubbling chlorine gas throughliquid benzene in the presence of ferric chloride catalyst. In an undesired side reaction, the product is further chlorinatedto dichlorobenzene, and in a third reaction the dichlorobenzene ischlorinated to trichlorobenzene. The feed to a chlorinationreactor consists of essentially pure benzene and a technical gradeof chlorine gas (98 wt% CL2, the balance gaseous impurities with anaverage molecular weight of 25) The liquid output from thereactor contains 65 wt% C6H6, 32 wt% C6H5CL, 2.5 wt% C6H4Cl2, and.5% C6H3Cl3. The gaseous output contains only HCl and theimpurities that entered with the chlorine. Find :
1. Percentage by which benzene is in excess,
2. The fractional conversion of benzene,
3. Fractional yield of monochlorobenzen,
4 Mass ratio ofthe gas feed to liquid feed.

Nconcentration refers to the molar concentration of an ion in solution. it may be identical to, or greater or less than, the molar concentration of the compound containing the ion that was used to make the solution. for soluble salts, the molarity of a particular ion is equal to the molarity of that compound times the subscript for that ion. for example, 1 m of alcl3 is 1 m in al3+ and 3 m in cl−. 1 m of (nh4)2so4 is 2 m in nh4+ and 1 m in so42−. part a what is the concentration of k+ in 0.15 m of k2s? view available hint(s) nothing m m part b if cacl2 is dissolved in water, what can be said about the concentration of the ca2+ ion? view available hint(s) if is dissolved in water, what can be said about the concentration of the ion? it has the same concentration as the cl− ion. its concentration is half that of the cl− ion. its concentration is twice that of the cl− ion. its concentration is one-third that of the cl− ion. part c a scientist wants to make a solution of tribasic sodium phosphate, na3po4, for a laboratory experiment. how many grams of na3po4 will be needed to produce 550 ml of a solution that has a concentration of na+ ions of 0.700 m ? express your answer numerically in grams. view available hint(s) mass of na3po4 n a 3 p o 4 = nothing g provide feedback

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

How do you identify the anode on a power source such as a battery? how do you identify the cathode? how are terms anion and cation?
