Hi Please answer the questions below. I do not need an explanation. Just the correct answer. Thank you! QUESTION 1 6 points Save Answer Consider a system Ax=b. Suppose the system has more equations than unknowns. Then it is possible for the system to have a unique solution. O O True False QUESTION 2 6 points Save Answer [-2 Given A=1 ( 9 3 1] -2 6 an 1 0 -1] , the (3,1)-entry of (A + B)' is [a]....
Hi, I need help in these two questions, mostly on setting up the equations. Also, how different is it that this question is asking for molarity of "sodium chromate soln" and not "sodium dichromate soln."? thanks in advance! 1. Chromate and ferrous ions react in acidic solution to form chromic and ferric ions, respectively. If 0.9422 grams of iron(II) bisulfate dissolved in sulfuric acid solution requires 24.83 mL of sodium chromate solution for complete titration, what is the molarity of...
Hi , I need your help please. I don't know how to do this . I posted this question before and some sweet person did all this work below but I don't really understand ( i also don't know if it's right)and he also did the GRAPH on paper .I Need the GRAPH on EXCEL PLEASE. If you kindly maybe type it so I can fill this chart that would be really great ( I just gotta show some work...
i need help with this lab please. can i get someone to answer the entire thing. thank you Instructor Equilibria of Coordination Compounds OBSERVATIONS AND DATA 1. The formation of complex ions with ammonia The net ionic equation for the reaction of excess Cuso, with NH, is 24 Cu2+ + 4NH3 [cu (NH3)4] The predicted effect on the reaction above of adding excess NH, (based on Le Châtelier's principle) is The reaction will shift to the night and product formation...
