Rusting of iron occurs in the presence of moisture according to the following equation: 4Fe(s) 3O2(g) : 2Fe2O3(s) Suppose that 3.19% of a heap of steel scrap with a mass of 1650 kg rusts in a year. What mass will the heap have after one year of rusting

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
