4. tonipoo610

i need step by step explaining because i keep on getting stuck at the oxygen

5. NotTim

I think you could use fractions too....

6. tonipoo610

i no the answer to the problem but i just cant figure out how to get it

7. NotTim

also, this image|dw:1357708177746:dw| is a little bit confusing

8. tonipoo610

the answer is 2 C2H6 + 7 O2 ---------> 4 CO2 + 6 H2O

9. tonipoo610

but i just dont know how people got it

|dw:1357708457062:dw| Blanace the Hydrogens at the end. Now, what do you do first?

12. tonipoo610

do you balance carbon first?

13. NotTim

why not

14. tonipoo610

but then oxygen has 5 atoms since you have to put a 2 coefficent on co2

15. tonipoo610

so how would you balnce the other oxygen

16. NotTim

ok. now what about the hydrogens (worry about oxygen after)

17. tonipoo610

i put a 3 in the products hydrogen but doesnt that make the products oxygen 5 as well UGG

18. NotTim

Why not 5/2 for Oxygen on the left side?

19. tonipoo610

my teacher said we cant use fractions

20. NotTim

really? What grade is this?

21. NotTim

well, if that's the case, why not just multiply the values by 2?

22. tonipoo610

8th grade

23. tonipoo610

nvrmind i guess i will just wing it lol

24. NotTim

25. tonipoo610
