chemistryishard Posted December 29, 2005 Report Share Posted December 29, 2005 C5H12O + O2 CO2 + H2O the numbers in dark red are ment to be subscript: can anyone help me balance this equation, i can not. Quote Link to comment Share on other sites More sharing options...
TIDUSGIYA Posted December 29, 2005 Report Share Posted December 29, 2005 The Fact That You Have Numbers In Your Equation Is Irrelivent. C5h12o + O2 Co2 + H2o C5h120 Is Alcohol, Added With Oxygine Will Give You Co2 This Effect Would Give You Water Or H20. To Balance This Out Would Be. Alcohol + O2 = Co2Co2 + Water Or (h20) = Ice. Whats The Balance. Quote Link to comment Share on other sites More sharing options...
P-man Posted December 30, 2005 Report Share Posted December 30, 2005 Well to actually balance the equation the numbers are relevant. Yet I can't seem to balance this one aout either. It's rather tricky, with an odd number of C and O atoms and an even number of H atoms. Quote Link to comment Share on other sites More sharing options...
MortenS Posted December 30, 2005 Report Share Posted December 30, 2005 I will take this stepwise: C5H11OH + O2 -> CO2 + H2O 1. Count the number of C's on each side: 5 on left, and 1 on right side:2. Multiply CO2 with 5 We are now at: C5H11OH + O2 -> 5CO2 + H2O 4.Now count the number of H's on each side: 12 on left, side, 2 on right side. 5. To balance hydrogen, multiply H2O with 6 We now have: C5H11OH + O2 -> 5CO2 + 6H2O 6: Count the O's on each side to find out if there is any imbalance in oxygen: 3 on left side, 16 on right side. We need 13 more O on the left side, and the only allowed molecule to add now is more oxygen. Here comes the trick: use fractional molecules while balancing the equation: We add 6.5 molecules of O2 (which equals 13 atoms of O), and get a total of 7.5 O2 molecules on the left side. We now have: C5H11OH + 7.5O2 -> 5CO2 + 6H2O We usually do not present balanced equations with fractions, so to get rid of the fraction, we multiply the whole equation with 2: 2C5H11OH + 15O2 -> 10CO2 + 12H2O 10 C on left, 10 C on right24 H on left, 24 H on right32 O on left, 32 O on right Quote Link to comment Share on other sites More sharing options...
P-man Posted December 31, 2005 Report Share Posted December 31, 2005 Cool trick. I tried to use it but I couldn't get it to work. Quote Link to comment Share on other sites More sharing options...
