Question

Gaseous ethane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 21. g of ethane is mixed with 132. g of oxygen. Calculate the maximum mass of water that could be produced by the chemical reaction. Round your answer to significant digits.

Answer 1

In given Infirmation Ethane + O2 CO2 + Hao CH₂CH3 + O2 - Cat H2O balance above reaction hot +702. 202 + 3H20 imele of CH₂ CH3 reacts Imoles of a to obtain a moles of Соъ and 3 moles of the Oh Chz 2002 + 3 lho 44 g/mol 18 almal CH28) mut 30-9/mole ; 32 g/mol Corner Co2 gwrn weight algm 13 agganas Converted into 21 gam : 132 gr. moles - 30. gammole 2n grelnole number of = weight ameles molecular weight = 0.7meles. = 4.125 mele - Means 0.7 moles of Choltz reacts with 4.125 mole of 02. It is clear that Chich is limiting agent. 9. I moles of Chetty required Of I moles of Oz; but 4.125 = Susmale moles of O2 i present. from chemical reaction, we can say that Imole of ChCH3 produce zmoles of 1420 which mean folm H2o in 3 times of Chz Clt. Here 0.7 moles of CHalty Consumed so (0.5x 3) moles of 10 Ho will folm. [amoles of the) Converted into weight = moles rest - 2 mees x m = 37-8 gum of toho males
