An extraction was performed as follows: 5.00 mL of 8.0 % ethanol (CH3CH2OH) in water was mixed with 5.00 mL of pentanol (CH3(CH2)4OH) and a small amount of NaCl. The organic layer of the extraction was analyzed and it was determined that the percent ethanol in the organic layer was 6.3 %. Calculate the partition coefficient for this extraction.

8.98 dm3 of hydrogen gas is collected at 38.8 °c. find the volume the gas will occupy at -39.9 °c if the pressure remains constant.

Listenbase your answer to the question on the information below.nuclear radiation is harmful to living cells, particularly to fast-growing cells, such as cancer cells and blood cells. an external beam of the radiation emitted from a radioisotope can be directed on a small area of a person to destroy cancer cells within the body.cobalt-60 is an artificially produced radioisotope that emits gamma rays and beta particles. one hospital keeps a 100.0-gram sample of cobalt-60 in an appropriate, secure storage container for future cancer treatment.which choice represents the correct product for the beta decay of the co-60? fe-60ni-60fe-61ni-61
