Additional Pyro Valence Problems

A flare composition is 15% KCIO4, plus it contains strontium nitrate (a second oxidizer) and magnesium (fuel). What will be the composition of the stoichiometric mixture Assume that Sr(N03)2 forms SrO, N2, and oxygen. [Pg.29]

The magnesium will form MgO, and KCIO4 will form KQ and oxygen (which combines with Mg and Sr). [Pg.30]

A flare mixture contains 45% Ba(N03 2,35% Mg, and 20% polyvinyl chloride (PVC, C2H3CI polymer). Is this mixture fuel rich or fuel lean [Pg.30]

Ferric oxide (Fe203) and boron (B) make an interesting low-toxicity delay mixture. What is the composition of the stoichiometric mixture, assuming that the reaction products are Fe and BjOj Valences are -6 for ferric oxide and +3 for boron. [Pg.30]

Aluminized ammonium nitrate-fuel oil (aluminized ANFO) is a popular commercial explosive. If a mixture contains 5% A1 by weight, what weights of ammonium nitrate (valence = -2) and fuel oil will make up the stoichiometric mixture Assume that ammonium nitrate forms Nj, 2 HjO, and evolves 1 O atom per formula unit. Also assume that fuel oil can be represented by -CH2-, with a molecular weight of 14 and a valence of +6. [Pg.30]
