Use lowest whole number coefficients. combustion reaction: CH +02 - CO, +H,0 A conbustion reaction occurs between 9.5 mol O, and 143 g C, H. Upon completion of the reaction, is there any CH remaining? Yes, there is still C, H, remaining, No, all of the C, H, is used up in the reaction. about us Careers privacy policy Termo c ontact

Answer 1

Answer Given combustion reaction Ca Hq +0g - CO + H₂O Now, Balance combustion reaction Ca HQ + 30 210 g + 2 H₂O weight of Ca Hd = 143 g molecules weight of Ca H4 = 28 g/mal. males = weight of Ca Ha Molecules weight of C2H4 = 1438 28 Il male = 143 mal. = soll mal. For the complate combustion of a Hq - for I mole alte required 3 mally of oxygen (2) 1 male ca Hq required: 3 mots og soll male al required = 3x5.11 mats og

Total required og = 15.33 mole. But we have only gos mole og > yes, there is still o Ha remaining. due to incomplute combustion of Ca H4. hare oxygen (d) is limiting reagent 3 mole of Of combustion = 1 mole Cq H4 mole of Of consumed by = h mole C2H4 gis mole of Og consumed by = gis male cana Ondly gis male colla combustion. Remaining amount of Ca He = Total - (combustion Ca HA) = S:11 - gos = 15.33 -9.5 = 5,83 = 1.94 male. 3 Remaining Cat4 = 1.94 mole
