A sample of dry air has an initial pressure (p1) of 1013hPa and temperature (T1) of 312K. It undergoes a process that takes it to new pressure of 600hPa with unchanged temperature (T2). Compute the mechanical work per unit mass performed by the sample under the following scenarios: a) Isochoric pressure reduction to p2 pressure followed by isobaric expansion to final state (5 points

Sodium sulfate dissolves as follows: na2so4(s) → 2na+(aq) + so42- (aq). how many moles of na2so4 are required to make 1.0 l of solution in which the na concentration is 0.10 m?

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
