Hey all, this is my first post so don\’t go flaming me from the start.
This is more of guidelines for people who want to make smoke bombs that perform complete combustion.
I\\\’m in grade 11 chemistry, so bear with me, everythings a bit crude...
Ok so the formula for smoke bombs is knox and sugar. everyone knows that. But what are the exact proportion to mix the 2 together? Most sites say 3/2 (6/4), a few say 7/3. So I looked into it.
Ok... (Summary at bottom)
FORMULA:
5 C12H22O11 + 48 KNO3 -> 36 CO2(g) + 55 H2O(g) + 24 N2(g) + 24 K2CO3
There is 3 times more knox than sugar...
(Yes I call it knox. For those retards who haven\\\’t caught on, I\\\’m talking about potassium nitrate (KNO3), but im sure most of you aren\\\’t THAT dumb.)
______________________________________________
All masses are in moles.
Formula: K1N1O3
Average mass : 101.1032
K ( 39.098) : 38.671 %
N ( 14.006) : 13.853 %
O ( 15.999) : 47.474 %
Formula: K1N1O3
Monoisotopic mass : 100.9515
K ( 38.963) : 38.596 %
N ( 14.003) : 13.871 %
O ( 15.994) : 47.532 %
48 KNO3 = 4848 moles
----------------------------------------------
Formula: C11H22O11
Average mass : 330.2890
C ( 12.011) : 40.001 %
H ( 1.007) : 6.713 %
O ( 15.999) : 53.284 %
Monoisotopic mass : 330.1161
C ( 12.000) : 39.985 %
H ( 1.007) : 6.716 %
O ( 15.994) : 53.297 %
5 sugar = 1650 moles
_____________________________________
So rougly, the exact proportions are:
4848 / 1650
But for anyone who is too lazy to scoop 6498, 3249, 1083, or 361 etc. scoops of chemicals, here is a simplified fraction, rounded to the nearest 10,000th:
10.1/3.4375
10 KNOX to 3.5 sugar.
please vote i need the points.
also let me know if there\’s any errors/improvements. I want to make the perfect smokebomb. After I do I\’m going to try to make some greek fire. =D damn those greeks rocked! |

thanks for the info but i doubt i’ll use it. i can relate to you needing points so i’ll be nice and give you a 5 |

do you know what the / means? it means cp. unless you put it on microsoft word or something like that. |

I apologize for the slashes. I copied it into notepad because i needed some points before i could post, and didn’t notice when i copied it back.
Also, please remember that when you measure out the proportions of chemicals, do NOT do it by VOLUME, measure them out by MASS.
(eg. 10 spoons/3.5 spoons vs. 10 grams/3.5 grams)
sugar is 3x heavier than knox, and it will skew your results. |

Please, if you aren’t going to vote, at least comment on what i’ve done. I would greatly appreciate feedback. |

this is very helpful. I wasn’t aware that there was so many different arguments for how much of each chemical to use. this is great |

good info. but i dout that ill use it.
even though i need to make smoke bombs. |

excelent, i have an extensive chemistry background and the informaition is all correct. thank you for doing half my work on calculating moles and mass. |

thank you! 4* |
