How many milliliters of 0.424 M KMnO4 are needed to react with 5.06 g of iron(II) sulfate, FeSO4?
The reaction is as follows: 10 FeSO4 (aq) + 2 KMnO4 (aq) + 8 H2SO4 (aq) → 5 Fe2(SO4)3 (aq) + 2 MnSO4 (aq) + K2SO4 (aq) + 4 H2O(l)
Making plastic drinking bottles for bottled water requires about 58 million barrels of oils per year (2007). In 2007, 300 million people averaged 114 L of bottled water per person. The average cost of 0.6 L was $1.00. The average charge for tap wa..
Explain how are excess sulfuric acid and the excess methanol removed from the crude ester after the reaction has been completed
The standard molar entropy for Br2(g) is 245.46j/(mol*K) at 25 degrees Celsius. Given that delta S=104.58J/K for the dissociation of one mole of Br2(g) into Br(g) at 25 degrees, find the standard molar entropy for Br(g) at 25 degrees Celsius.
