Question
3. When solid tin comes in contact with the oxygen in the air,solid tin (IV) oxide is formed. a. Write a complete balanced equation from the reaction (showratio) b. A piece of tin foil, 8.25cmx 21.5 cmx0.600mm is exposed tooxygen. (d=7.28g/cm3) Assuming that all the tin has reacted , what is the mass ofthe oxidized tin foil? c. Air is about 21.0% oxygen by volume (d=1.309g/L). How manyliters of air are required to completely react with the tinfoil? 3.

Air is about 21.0% oxygen by volume (d=1.309g/L). How manyliters of air are required to completely react with the tinfoil?Explanation / Answer
We Know that : Sn + O2 ------> SnO2 Tin (IV) Oxide The Massof Tin gets Oxidized is : Volume x density 10.6425 cm3 x 7.28 gm / cm3 = 77.477 gm. The Volume ofOxygen reacted i s : 21 gm of Oxygen i s Present if we assume the total weight ofair is 100. Volume = weight / density = 21 gm / 1.309 gm / L = 16.0427 L of O2 has been used to oxidizecompletely. = 77.477 gm. The Volume ofOxygen reacted i s : 21 gm of Oxygen i s Present if we assume the total weight ofair is 100. Volume = weight / density = 21 gm / 1.309 gm / L = 16.0427 L of O2 has been used to oxidizecompletely. =Related Questions
