sir ji isme nikalna kya hai? density of hydrocarbon?
@iTeachChem I think I got an approach
1. Write a general combustion eqn in terms of x and y
2. Use pm=rhoRT find Mavarage
3. We know Mav is weighted avarage of co2 and h2o with weights x and y/2 and you get one more equation
4. Solve for x and y and find enthalphy
sounds good, can you gimme the answer?
There is only one equation relating x and y idk why I thought there was 2
But
x/y = 5.55/14.9=0.372=3/8?
c3h8?
@iTeachChem
I'll plug in values
Is -210kj/mol the answer?
sounds about right! nicely done
can you show me the math behind this please?
3 CO2 4 H20 - hf c3h8 = dh rxn right?
Yeah
I'll send it in a bit
@iTeachChem
can we use high level isodemic
reactions?
but it would probably
be error
Way to go
Kahe. Needle is better suited than a hammer here
aha
What's that
Pic thodi clear nhin dikh rhi h sir
