The value of Ka for nitrous acid (HNO2) at 25 ∘C is 4.5×10−4. Part APart complete Write the chemical equation for the equilibrium that corresponds to Ka. H+(aq)+NO−2(aq)⇌HNO2(aq) HNO2(aq)⇌H+(aq)+NO−2(aq) HNO2(aq)⇌H−(aq)+NO+2(aq) HNO2(aq)+H+(aq)⇌H2NO+2(aq) HNO2(aq)+H−(aq)⇌H2NO+2(aq) By using the value of Ka, calculate ΔG∘ for the dissociation of nitrous acid in aqueous solution.

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
