Explain why group 7 elements react in a similar way with iron. Why atoms in the same group on the periodic table act similar chemically to one another? Why do groups among the main-group elements display similar chemical behavior? Why does hydrogen not have the characteristics...
Why we do not use HNO_3 and HCl in iodometry? Why does the more stable the carbocation intermediate make the rate of dehydration faster? Explain why NaH and H2S have different degrees of ionic character? Explain why nitrobenzene reacts with electrophiles at a different rate than benzene. ...
KMnO4 oxidies HCl to chlorine.Why is HCl not used to acidify a permanganate solution in volumetric estimation of Fe^(2 + ) or C2O4^(2-) ?
You will watch iron reacting with hydrochloric acid and beautiful yellow sulfur floating on top of it! :-D The only reaction possible is: Fe + 2 HCl → H2 + FeCl2 The elemental sulfur will not react in aqueous environment! VOTE Allison...
Entropy (a) Using the equation for the entropy of mixing, calculate the energy change at freezing. (b) How does this compare with the enthalpy of solidification? (c) Are the two interchangeable? Explain why or why not. Which...
How does electrolyte conductivity affect corrosion rates? Why is copper (II) sulfate solution a good conductor of electricity? Why are galvanic cells kept in two different half-cells? Explain why aluminum does not react with potassium nitrate (KNO3) although it reacts...
When washed into a drain, an azide could react with the lead in the piping to form lead azide. Because the detonation of lead azide could destroy a major portion of a sewer system, and azide should not be discharged into a drain. W...
which does not use minimal energy throughout its lifespan may not be regarded as Green [15]. Combining both requirements of a building's performance results in an environment that is expected to be environmentally sustainable with a conducive indoor environmental quality (IEQ) for occupants' use....
How does it react with the aspirin? What is the value of the van 't Hoff factor for HCl? What is meant by the capacity of a buffer? Describe a buffer with low capacity and the same buffer with greater capacity. What is meant by running a buffer in Electrophoresis? What...
Fe(s) + H2 O(g) A) [H2O][H2] B) [Fe][H2O][H2] C) [Fe][H2O][FeO][H2] D) [H2][H The equilibrium constant for acid dissociation of acetic acid, Ka, is 1.8 x 10-5. Explain what this tells us about the favored direction of the equilibrium (i.e. ...
