Given that
2al(s)+3/2o2(g)> al2o3(s) deltahrxn=-1601kj/mol
and
2fe(s)+3/2o2(g)> fe2o3(s) deltahrxn=-821kj/mol
calculate the standard enthalpy change for the following reaction.
2al(s)+fe2o3(s)> 2fe(s)+al2o3(s)

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
