Dinitrogen tetraoxide

Sn are combined in a 2 1 molar ratio in liquid Brp3 (equation 9.68). 

In contrast to the situation for H2SO4, where we noted that it is difficult to separate reaction products from the solvent by evaporation, BrPs can be removed in vacuo (AvapTT = 47.8 kJ mol ). The syntheses of many other inorganic fluoro-derivatives can be carried out in a similar manner to reaction 9.67 or 9.68, and equations 9.69-9.72 give further examples. 

Some of the compounds prepared by this method can also be made using F2 as the fluorinating agent, but use of F2 generally requires higher reaction temperatures and the reactions are not always product-specific. 

Non-aqueous solvents that behave similarly to Brp3 in that they are good oxidizing and fluorinating agents include CIF3, BrPs and IF5. 

When AgF and SbFs are dissolved in BrFa, the product is Ag[SbFg]. Comment on the role of the solvent in this reaction. 

When tungsten metal dissolves in BrFa, a W(VI) compound is formed, (a) What is this product (b) The oxidation must be accompanied by a reduction process. Suggest the likely reduction product.

To illustrate how a relatively simple equation can be written and balanced, consider a reaction used to launch astronauts into space (Figure 3.4). The reactants are two liquids, hydrazine and dinitrogen tetraoxide, whose molecular formulas are N2H4 and N204, respectively. The products of the reaction are gaseous nitrogen, N2, and water vapor. To write a balanced equation for this reaction, proceed as follows ... 

This is the final balanced equation for the reaction of hydrazine with dinitrogen tetraoxide. Three points concerning the balancing process are worth noting.

Rapid passage of gas into a cone, nitrate solution caused an explosion, or ignition of a slower gas stream. The explosion may have been caused by rapid oxidation of the precipitated silver phosphide derivative by the co-produced nitric acid or dinitrogen tetraoxide. 

Mixtures of aluminium powder with liquid chlorine, dinitrogen tetraoxide or tetran-itromethane are detonable explosives, but not as powerful as aluminium-liquid oxygen mixtures, some of which exceed TNT in effect by a factor of 3 to 4 [1], Mixtures of the powdered metal and various bromates may explode on impact, heating or friction. Iodates and chlorates act similarly [2], Detonation properties of gelled slurries of aluminium powder in aqueous nitrate or perchlorate salt solutions have been studied [3], Reactions of aluminium powder with potassium chlorate or potassium perchlorate have been studied by thermal analysis [4],...

Magnesium perchlorate contained in a glass tube between wads of cotton wool was used to dry a mixture of oxygen and dinitrogen tetraoxide. After several days the drying tube exploded violently. It seems probable that the acidic fumes and cotton produced cellulose nitrate, aided by the dehydrating action of the perchlorate.
