With a solution in them connected by a liquid salt bridge junction filled with KNO3. In one solution you have a graphite electrode that is connected with a wire to a copper electrode in the second soution. The soution in contact with the graphite electrode consists of dissolved Sn(NO3)2. The solution in contact with the copper electrode consists of dissolved CuNO3.
a) write the standard half cell reduction reaction equation for each solution?
b) what are the standard half cell potentials; E anode and E cathode?
c) If the electrochemical cell is allowed to operate as a gavanic cell, which solution species will be oxidized, which solution species will reduce?
d) write the sybolic representation for the galvanic cell.
e) what would "standard conditions" for this galvanic cell be?
f) If the cell is at standard conditions, determine the cell potential(E cell).
How many moles of KMnO4 are present in 25.0 mL of a 0.0900 M solution?
Give two reasons why the product is concentrated in the distillation flask during a continuous solid-liquid extraction. 2) what difficulties may be encounter during the determination of the melting point of caffeine?
Draw the major organic product(s) formed when hex-2-yne undergoes hydration in the presence of HgSO4 and H2SO4.
Calcium phosphate, silicon dioxide, and coke may be heated together in an electric furnace to produce phosphorus, as shown in the following equation: 2Ca3(Po4)2+6SiO2+10C=6CaSiO3+10CO +P4
Methyl salicylate, C8H8O3, the adorous constituent of oil of wintergreen, has a vapor pressure of 1.00 torr at 54.3 degrees celsius and 10.0 torr at 95.3 degrees celcius. What is it's vapor pressure at 25 degrees celcius?
what is the reaction order? If the unit is M^-1 s^-1, what is the reaction order? Use the rate laws to determine the unit for the rate constant.
Nitrate ion (NO2)^(-1) can be analyzed by creating an acidic solution of nitrite ion and adding excess iodide (I)^(-1) ions creating NO and I2. The I2 combines with excess (I)^(-1) to create (I3)^(-1).
Two volatile liquids (A and B) form an ideal mixture at 300.0K which just begins to boil at a pressure of 0.3000 atm. The vapor pressure of pure component A is 0.5000 atm and the vapor pressure of pure component B is 0.2000 atm
