5.88. military explosives explosives called amatols are mixtures of ammonium nitrate and tnt introduced during world war i when tnt was in short supply. the mixtures can provide 30% more explosive power than tnt alone. above 300°c, ammonium nitrate decomposes to n, o, and h, o. write a balanced chemical reaction describing the decomposition of ammonium nitrate, and determine the standard enthalpy of reaction by using the appropriate standard enthalpies of formation from appendix 4.

Explanation:

2NH₄NO₃(s) ⟶ 2N₂(g) + O₂(g) + 4H₂O(g)

The formula for calculating the enthalpy change of a reaction by using the enthalpies of formation of reactants and products is

                          2NH₄NO₃(s) ⟶ 2N₂(g) + O₂(g) + 4H₂O(g)

ΔH°f/kJ·mol⁻¹:         -365.1               0            0        -241.8

fe 55.85 g/mol and h2o 18.02 g/mol.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
