Re: Is the stoichiometric coefficient of this chemical reaction correct?

I ignited an Mg/PVDF composite with magnesium and polyvinylidene fluoride (PVDF) in air. I wonder if the equation I wrote down is correct.

Is the stoichiometric coefficient of this chemical reaction correct?

4Mg + 2O2 + 3(C2H2F2) = MgO + 3H2O + 3MgF2 + 6C

Re: What are the reaction products of this substance?? please help!

(C5O2H8)n is PMMA, Poly(methyl 2-methylpropenoate).

I ran DSC analysis of both materials in a nitrogen atmosphere and I need to calculate the theoretical ΔH, so I want to know what the reactants are. :D

Re: Why doesn't Si + Wo3 ignite?

oh i see, Maybe it’s because of the activation energy.
and I raised it to about 800 degrees, but there is no ignition. :D
Thanks!

please help me calculate stoichiometry

In some papers, 6.41KNO3 + 1.027C12H22O11 → 7.97H2O + 3.88CO2 + 3.205N2 + 6.06K2CO3

What I calculated is

48 KNO3 + 5 C12H22O11 = 36 CO2 + 55 H2O + 24 K2CO3 + 24 N2

How does the above equation come out?
