Hi there! Since you have posted multiple questions, we will answer the first one for you.

You left a bowl of refried beans in the refrigerator too long. One day your roommate opens the fridge and it smells like rotten egg (due to generated hydrogen sulfide, H2S). You immediately run to the store to purchase activated charcoal to remove the odor. From a quick search online you learn that the linear partitioning coefficient is 30 m/kg. Assuming that the refrigerator volume is 0.5 m?, the initial odor concentration is 3.2 µg/m3, and the final concentration is 0.3 µg/m3 , calculate the minimum mass of adsorbent (in g) you need to purchase.

Question

You left a bowl of refried beans in the refrigerator too long. One day your roommate opens the
fridge and it smells like rotten egg (due to generated hydrogen sulfide, H2S). You immediately run to
the store to purchase activated charcoal to remove the odor. From a quick search online you learn
that the linear partitioning coefficient is 30 m/kg. Assuming that the refrigerator volume is 0.5 m?,
the initial odor concentration is 3.2 ug/m³, and the final concentration is 0.3 ug/m3 , calculate the
minimum mass of adsorbent (in g) you need to purchase.
Enter your final answer with 2 decimal places.
It is proposed to add activated carbon to treat a storm stream with a pollutant concentration of 5.1
mg/L. If the treatment plant has only 22 kg of activated carbon, how many liters of waste stream can
be treated to achieve an equilibrium effluent concentration of 2.0 mg/L? Lab tests show that
Freundlich isotherm coefficients for the activated carbon and the pollutant are K, 0.09 L/kg and n
= 2.8 for concentrations in g/L.
Enter your final answer with 2 decimal places.

tha General Chemistry II Laboratory Manual, 2021 Revision H 39 Questions: lins dod ich mus 1) When you set up the temperature probe using Capstone, you did not calibrate it to read the correct temperature. It's possible that the probe reads temperatures that are consistently off by 1 or 2°C. Why won't this affect your results for this experiment? Explain your answer P12.20
Iodine is sparingly soluble in water but much more so in carbon tetrachloride. The equilibrium constant, also called the partition coefficient, for the distribution of I2 between these two phases I2(aq) =12(CCI4) is 83 at 20°C. (a) A student adds 0.028 L of CCI4 to 0.213 L of an aqueous solution containing 0.037 g I2. The mixture is shaken and the two phases are then allowed to separate. Calculate the fraction of I2 remaining in the aqueous phase. 4.0 (b) The student now repeats the extraction of I2 with another 0.028 L of CCI4. Calculate the fraction of I2 from the original solution that remains in the aqueous phase. 4.0 (c) Compare the result in (b) with a single extraction using 0.056 L of CCI4. Comment on the difference. After a single extraction using 0.056 L of CCI4, the fraction of I2 that remains in the aqueous phase is 40 This result is larger than the result in (b), which means that a single large extraction is not as efficient as two separate smaller extractions.
