What mass of co is needed to react completely with 55.0 g of fe2o3 in the reaction: fe2o3(s) + co(g) → fe(s) + co2(g)?

the balanced equation for the reaction is as follows

Fe₂O₃ + 3CO ---> 2Fe + 3CO₂

stoichiometry of Fe₂O₃ to CO is 1:3

mass of Fe₂O₃ reacted - 55.0 g

therefore number of Fe₂O₃ moles reacted - 55.0 g / 159.7 g/mol = 0.344 mol

according to molar ratio

number of CO moles needed is 3 x number of Fe₂O₃ reacted

therefore number of CO moles required - 3 x 0.344 mol = 1.032 mol

mass of CO required - 1.032 mol x 28 g/mol = 28.9 g

28.9 g CO

Explanation: I just took the quiz and it was correct:)

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
