An electrolytic cell is constructed to produce aluminum metal and chlorine gas from aluminum chloride (AlCl3).
A. Write the half-reaction that occurs at the anode:
B. Write the half-reaction that occurs at the cathode.
C. Write the balanced equation for the net reaction.
D. Calculate the standard cell potential (E?cell).
E. How many grams of aluminum metal and how many liters of chlorine gas can be produced by passage of 4.8 amp of current for 2.3 hour under standard conditions (25?C and 1 atm pressure)?
If atmospheric pressure suddenly changes from 1.00 atm to 0.898 atm at 298 K, how much oxygen will be released from 3.10 L of water in an unsealed container?
A 4.5 g nugget of gold absorbed 276 j of heat. What was the final temperature of the gold if the initial temperature was 25 OC ? The specific heat of gold is 0.129 j/g OC.
Which of the following compounds would you expect to be ionic?
0.01M HCl reacts with 3.18 g Na2CO3. Here 50 mL of HCl is required for the reaction. Calculate the volume of CO2 produced at 273 K and 1 atm.
When Copper (II) sulfate is prepared from copper (II) nitrate and sodium sulfate, the reaction initially produces a hydrated product: Cu(NO3)2 + Na2SO4 + 5H2O yield CuSO4 x 5 H2O + 2 NaNO3
Assuming the heat absorbed by the styrofoam is negligible, calculate the expected final temperature. The specific heat of water is 4.184 J g-1 K-1.
Which of the following will not have ionic bonds?
The specific heat capacity of silver is 0.240 J/(g x degrees C). Calculate the energy (in kJ) required to raise the temperature of 263 g Ag from 273K to 278 K.
A student standardized her I2 solution by preparing a solution of 0.0450 g of ascorbic acid (vitamin C) in a 100 mL volumetric flask. She titrated several 10.00 mL samples of the Vitamin C solution
What is the pH of a buffer prepared by adding 0.809mol of the weak acid HA to 0.305mol of NaA in 2.00L of solution? the dissociation constant Ka of HA is 5.66x10^-7
Determine the molar amounts of NO, O2 and NO2 after a complete reaction. NO=? O2=? NO2=?
The next question was this: "What is the PH at it's equivalence point? AS part of your answer, define equivalence point. What does it mean for a substance to be at its equivalence point?"
