b Iron metal reacts with chlorine gasgivingron 3 C12(g) ronI) chloride. The balanced chemical e chloride. The balanced chemical equation for this reaction is: 2 Fe(s) 2 FeCl3(s) Beginning with 26.0 g of iron, what mass of Cl2, in grams, is required for complete reaction? What mass of FeClj can be produced? g Cl g FeCl3

Solution

molar mass of Fe = 55.845 g/mol then 26 gm of Fe = 26/55.845 = 0.46557 mole

According to reaction 2 mole Fe react with 3 mole Cl₂ therefore to react with 0.46557 mole Fe requied Cl₂ =

0.46557 X3 / 2 = 0.69836 mole of Cl₂

molar mass of Cl₂ = 70.9060 g/mole therefore 0.69836 mole of Cl₂ = 0.69836 x 70.9060 = 49.5 gm

49.5 gm Cl₂ required to completly react with 26 gm iron

According to reaction 2 mole Fe produce 2 mole FeCl₃ therefore 0.46557 mole of Fe produce 0.46557 mole FeCl₃

molar mass of FeCl₃ = 162.2 g/mol therefore 0.46557 mole of FeCl₃ = 0.46557 X 162.2 = 75.5 gm

75.5 gm FeCl₃ produced.
