Title: How many molecules of O2 would react with 56 C2H6 molecules according to the following balanced equation? Post by: rivers.butterfly on Feb 15, 2013 How many molecules of O2 would react with 56 C2H6 molecules according to the following balanced equation?
2C2H6 + 7O2>>>4CO2 + 6H2O Title: How many molecules of O2 would react with 56 C2H6 molecules according to the following balanced equation? Post by: tosha.garza on Feb 15, 2013 Well, 2 C2H6 molecules react with 7O2 molecules, therefore to find out how many O2 molecules react with 56 C2H6 do the following sum:
(56/2)*7 = 196 O2 molecules needed We now have the reaction equation: 56C2H6 + 196O2>>>112CO2 + 21H2O Title: How many molecules of O2 would react with 56 C2H6 molecules according to the following balanced equation? Post by: smmrwds on Feb 15, 2013 Look at the ratio between C2H6 and O2 (the coefficients in the balanced equation). This ratio is both the molecule ratio and the mole ratio.
56 C2H6 x 7 O2/2C2H6 = 196 Title: How many molecules of O2 would react with 56 C2H6 molecules according to the following balanced equation? Post by: ilikecrackers on Feb 15, 2013 2 molecules of Ethanol obviously need 7 molecules of O2.
Therefore 56 molecules of C2H6 = 7/2 x 56 = 196 mol. O2. Title: How many molecules of O2 would react with 56 C2H6 molecules according to the following balanced equation? Post by: Riyan on Feb 15, 2013 say what?!?!
Title: How many molecules of O2 would react with 56 C2H6 molecules according to the following balanced equation? Post by: smokebomb13 on Feb 15, 2013 if 2 C2H6 react with 7 O2 then 28*2(=56) C2H6 react with 28*7 O2 molecules = 196 O2 molecules out of my head, no calculator needed.
