balance equation- help (1 Viewer)

[speed_bump]

i really should be able to do this, but i cant so help me please-
can someone balance this------>

CH3OH + O2 -----------> CO2 + H2O


thankyou......

 

[ishq]

2ch3oh + 3o2 --> 2co2 + 4h2o

 

[speed_bump]

but isnt there now 11 oxygens on the left and only 8 on the products side, or am i just way overly confused on this......

 

[speed_bump]

dont worry..........im jst stupid........i figured it out....its been a while since ive had to do this sorta thing

Just follow four simple steps;

ALWAYS balance elements in the following order

• metals

• non-metals

• hydrogen

• oxygen

Remember to include states of mater in EVERY reaction, all substance in a combustion reaction (your example) are gaseous. So,

2CH₃OH(g) + O₂(g) ---> CO₂(g) + H₂O(g) + heat​

Hope that helps too.

Shouldn't that be dual arrow for equillibirum?

If it were a case where the heat was dissapating into the air then there probably wouldn't be much backwards movement would there?

P.S How are you notating a double arrow on this forum (<---->)?

It is a COMBUSTION REACTION (in other words, its a non-spontaneous redox reaction) these are not equilibrium systems.

thanks for the help......
my problem was that i was doing 2 * 3 =9. i was stuck on that forever..........................but yer thanks.

That'll teach me to read the entir post before commenting.

KFunk: Yeah, <--------> works
