Question

Homework - Unanswered How many grams of oxygen and carbon dioxide are consumed and formed, respectively, during the combustion of 100 grams of ethylene, H2C=CH2? O A 343; 313 0 B 171; 157 O C 513; 471

Answer 1

Correct option is option A

combustion of ethylene - . Cz tq + 02 . 102 + H2O. Balancing the above equation. . Cz Hq + 302 .2002 +2H2O 1 mole Calta reacts with 3 mol oz and produces 2 mol.co, I Now, molecular weight of Catty = 28.05 g komo " . of 02 3.16.00g of co2 = 94.01 g > 1

molecular weight of Caita = 28:05 g ? : of O2 = 32. vi o of CO2 = 49101 g Now, according to the above balanced equation 28.05g of ez tq reacts with (32x3) = 96 g of O2 and produces (49.01x2) = 88.02 g of eoz For consumption of O₂- 28.05 g of ethylene consumes go g of O2 i gn - hores g of oz 100 g " 96 » ~ 343 g of 02 28.0E Xloo 88.02 For production of co2- 28.05g of ethylene produces 88.02 g of coz Ag in 100 g " 88.02 yivo 3139 of coz so, 343 g of O2 is consumed 313 g of colis procluced
