Consider the reaction 4 Fe(s) + 3 O2(g) → 2 Fe2O3(s).
If 12.5 g of iron(III) oxide (rust) are produced from 8.74 g of iron, how much oxygen
gas is needed for this reaction?

try answer.com that works for me

58750.08068 is the answer i think

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
