Sr(IO3)2 + 2KNO3 Mols of Sr(NO3)2 used was .005023 Chemistry The homework question is : Calculate the Delta H for the following reaction: C6H6 + O2 -> C + H2O(l) State whether the reaction is exothermic or endothermic. ... IO3− + 6 H+ + 5 I− → 3 I2 + 3 H2O so as long as we avoid a stoichiometric excess of Iodide, loss due to tri-iodide (from iodate and excess iodide) may not be an issue after all. This program was created with a lot of help from: The book "Parsing Techniques - A Practical Guide" (IMHO, one of the best computer science books ever written. 2 0. Redox Reactions: A reaction in which a reducing agent loses electrons while it is oxidized and the oxidizing agent gains electrons, while it is reduced, is called as redox (oxidation - reduction) reaction. 1 decade ago. See the answer. #3. I2: I has an oxidation state of 0. 1 0. tormey. Pb(OH)42− + ClO− → PbO2 + Cl− This problem has been solved! Become a Patron! ClO2 Æ ClO2 -+ ClO3 -Cu(NH3)4 2+ + S2O4 2-Æ SO3 2- + Cu + NH3 . I2 + 10 HNO3 = 2 HIO3 + 10 NO2 + 4 H2O. The production of I2 in aqueous solution containing IO3- and nitrite (NO2-) at 25 °C was negligible. 0 0. BY OXIDATION NUMBER METHOD - 16865346 I'm pretty sure what I've done there is right.
