A. Here is the balanced equation 5Sn^2+ + 2MnO4^- + 16H^+ → 5Sn^4+ + 2Mn^2+ + 8H2O B. 43.75 ml of permanganate is required to titrate a 0.6493 gram sample of tin. Calculate the molarity of the KMnO4 solution
Like several other bonds, carbon-oxygen bonds have lengths and strengths that depend on the bond order. Draw Lewis structures for the following species, and arrange them in order of increasing carbon-oxygen bond strength. (Indicate the order with the numbers from the drop-down list, starting with 1 for the compound with the smallest bond strength to […]
Compare how heat flows during exothermic reactions and endothermic reactions. Explain what happens to the thermal energy of the surroundings in each case.
Consider the reaction mg(s)+fe2+(aq)→mg2+(aq)+fe(s) at 47 ∘c , where [fe2+]= 2.80 m and [mg2+]= 0.210 m . part a what is the value for the reaction quotient, q, for the cell? express your answer numerically.
By how many volts will the potential of mg2+ ion-selective electrode change if the electrode is removed from
Which pair of atoms forms the most polar bond? which pair of atoms forms the most polar bond? p and cl si and f si and cl p and f?
In solid NaCl, each sodium ion is surrounded by six chlorine ions and each chlorine ion is surrounded by six sodium ions. This arrangement results in a
I provided the guildline and some informtaion as well with a sample of how the report should look like. please follow it carefully and its 1-3 pages without th ecover page. NOTE: the sample that I download it has been uploded in weird format, so plz look at the guidline to make sure.
A solid sample of Fe(OH)2 is added to 450.0 mL of 0.550 M aqueous HCl. The resulting solution is acidic. It takes 95.0 mL of 0.500 M NaOH solution to neutralize the solution. Answer the following questions: How would you prepare 1.50 L of the 0.550 M HCl solution from a 12 M concentrated HCl Solution? […]
