A current of 0.0100 A is passed through a solution of rhodium sulfate, causing reduction of the metal ion to the metal. After 3.00 h, 0.038 g of Rh has been deposited. The charge on Rh is +3. What is the formula for rhodium sulfate?
Define the terms exothermic and endothermic. In a calorimetric experiment, how does one determine whether a reaction is one or the other?
The equivalence point is reached when 36 ml of HCl (titrant) is added. What is the pH at the equivalence point? (Kb of NH3 = 1.8 x 10-05) (a) For 36.0 mL of titrant, what is the pH?
draw the structures of the six diastereomers of the truxinic acids and the five diasteromers of the truxillic acids, clearly showing the photochemistry
In a voltaic cell, the anode is negative relative to the cathode. Oxidation occurs at the anode of either type of cell (voltaic and electrolytic).
write two equations that show thw two-stage ionization of sulfurous acis in water.(H2SO3) which stage of ionization is likely favored?
The mass spectrum of an organic compound shows the relative abundance of M to be 34.29% and M+1 to be 8.901%. Assuming the peaks are caused by 12C and 13C isotopes, determine the number of carbon atoms in the compound. Natural abundance: 12C is 98..
The half-equivalence point of a titration occurs half way to the end point, where half of the analyte has reacted to form its conjugate, and the other half still remains unreacted.
Why is glycogen debranching enzyme necessary? a) It allows regulation of the rate of glycogenolysis. b) Because glycogen phosphorylase cannot convert G1P to G6P
When setting temperature scan program of Diffrential Scanning Chromatography,
If your front lawn is 15.0 feet wide and 20.0 feet long, and each square foot of lawn accumulates 1350 new snow flakes every minute, how much snow (in kilograms) accumulates on your lawn per hour?
the 20 ml of water added to the erlenmeyer flask is to be previously boiled deionized water. Since water does absorb CO2 from the atmosphere and since CO2 dissolved in the water causes it to be slightly acidic
The equilibrium constant at 427°C for the reaction N2(g) + 3H2(g) 2NH3(g) is Kp = 9.4 × 10-5. Calculate the value of ΔG° for the reaction under these conditions.
