In a particular redox reaction, NO is oxidized to NO3- and Fe3 is reduced to Fe2 . Complete and balance the equation for this reaction in acidic solution. Phases are optional. NO + Fe^3+ ----->NO3^- + Fe^2+
Write the reactions for the preparation of the diaonuim salt for the coupling of the salt with the sodium salt of 2-napthol.
At 600 degrees C, the equilibrium constant for the reaction 2HgO(s) --> 2Hg (l) +O2 (g) is 2.8. Calculate the equilibrium constant for the reaction 1/2O2(g) + Hg(l) --> HgO (s)
Are the physical and chemical properties of a compound necessarily similar to those of the elements of which it is composed
how many millimoles of HNO3 are needed to react completely with a .2800 gram piece of copper wire.
What is the molarity of a solution prepared by adding 29.3 g of HNO3 to enough water to make 2 L of solution
Atmospheric pressure decreases as altitude increases. In other words, there is more air pushing down on you at sea level, and there is less air pressure pushing down on you when you are on a mountain
Suppose in the lab you measure 0.3951 g of NaOH and dissolve it into 100.0 mL of water. You then measure 0.1985 g of KHP and place it in a clean, dry 100-mL beaker, and then dissolve the KHP in about 25 mL of water and add a couple of drops of phe..
Use qualitative molecular orbital theory to explain why Na2O2 is diamagnetic and KO2 is paramagnetic (use the appropriate diagram from the notes. Use MO to explain the nature of the oxygen-oxygen bond in the complex anions). What is the oxygen-oxy..
Calculate the mass of ethylene glycol (C2H6O2) that must be added to 1.00 kg of ethanol (C2H5OH) to reduce its vapor pressure by 12.0 torr at 35C. The vapor pressure of pure ethanol at 35C is 1.00x10^2 torr.
