i need to know how to get the same # of o's h's &c's

2c2h6 + 5o2 = 2co2 + 6h2o

First get the carbons and hydrogens balanced by puting a 2 in front of CO2 and a 3 in front of H2O:
This gives C2H6 + O2 ---> 2CO2 + 3H2O
Then you notice the only thing unbalanced is oxygen. You need 7 equivs. of oxgen so put 3.5 (or 7/2) in front of the oxygen giving:
C2H6 + 7/2O2 ---> 2CO2 + 3H2O
Note that some teachers dont like to see fractions for balancing equations (but this is usually done after school) so they might want the following by multiplying by 2:
2C2H6 + 7O2 ---> 4CO2 + 6H2O

2C2H6+7O2->4CO2+6H2O
C=2=4 C=1=4
H=6=12 H=2=12
O=2=14 O=3=14
next time send something easier!

It's hard to explain it on the internet. If you have 4 O's, then you need 4 on the other side. Example: 4O + C---> O2 + C would change to 40 + C ----> 2 O2 + C. If you need more help, I'd suggest asking your teacher. =)

At a wager: TiO2 + 2C + 2Cl2 --> TiCl4 + 2CO C is a sturdy, Cl2 a gas (i think of) and CO is definately a gas. No clue approximately the different 2. Why no longer seem it up? you ought to have information tables or some thing.

the balancing is 2c2h6 + 7h2o ---> 4co2 + 6h2o

you need to have the same amount of C's, H's, and O's.... remember that this is a single replacement. does that help?
