AI Thread Summary
The discussion focuses on finding the balanced equation for propanol combustion and its kcal/gram value. The initial attempt at balancing the equation, CH3CH2CH2OH → 6CO2 + 2H2O, is incorrect, as the number of carbon, hydrogen, and oxygen atoms does not match on both sides. The correct balanced equation for propanol (C3H8O) combustion is CH3CH2CH2OH → 2CO2 + 4H2O. Additionally, the distinction between propanol (C3H8O) and propanal (C3H6O) is clarified, emphasizing the importance of identifying the correct compound before balancing. Understanding the combustion process and the correct chemical formula is essential for accurate calculations.

Homework Statement



I am trying to find a balanced equation for Propanol, and in addition - what is the Kcal/gram of Protonal


Homework Equations



I think I'm starting with CH3 CH2 CH2 OH (left side) and CO2 H20 (right side)

The Attempt at a Solution




CH3CH2CH2 OH to 6CO2 2H20 I'm not sure if that balances the equation or not. Additionally I have been trying to find information on Propanal being used as a bio fuel but all the sites I am able to pull up only talk about methanol and ethanol - what am I missing?

Thanks allot

When you balance a formula, the same number of atoms of each species must be balanced. I notice that you have

CH_3-CH_2-CH_2-OH \rightarrow\ 6CO_2 + 2H_2O

Is this balanced?
 
OK, so if I count up the atoms in the original formula - CH3 CH2 CH2 OH (left side) and CO2 H20 (right side)

C has 3 on the right 1 on the left
H has 8 on the right 2 on the left
O has 1 on the right 3 on the left

Then to balance is it CH3 CH2 CH2 2OH - 2CO2 4H20 ?

It should be: CH_3-CH_2-CH_2-OH \rightarrow\ 2CO_2 + 4H_2O
(but something(s) is wrong about it)

The way I see it there are three carbons on the left and 2 on the right.
There are 8 hydrogens on the left and 8 on the right.
There is one oxygen on the left and 8 on the right.

Is this balanced?

Propanal / Propanol ?

They are not the same thing, which one is it ?

One is C_{3}H_{8}O propanol (has 2 forms, propan-1-ol and propan-2-ol )

The other is C_{3}H_{6}O propanal


Before you even start balancing you need to know which chemical you actualy mean. From contact of burning of fuels I assume it is propanol and propan-1-ol at that.


P.S. What else is needed to make fire ... fuel + ?

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
