The thermal decomposition of sodium azide has been investigated in the temperature range 240–365°C. Sodium Azide [CAS No. B) How many grams of NaN3 are required to form 13.0 (g) of nitrogen gas? Answers: 1 on a question: The decomposition of sodium azide, NaN3(s), is used to inflate airbags. I am confused on . The mechanism of decomposition seems to involve excited azide ions (through internal conversion) and excitations. 2NaN3 (s) rightarrow 2Na (s) + 3N2 (g) A) How many moles of N2 are produced by the decomposition of 1.40 mol of NaN3? Executive summary: The explosivity of Sodium azide was tested according to the EU guideline A.14 (Explosive Properties). Write the balanced chemical equation for the decomposition of sodium azide. 26628-22-8] All users of sodium azide and sodium azide solutions should review this document. The heat from this ignition starts the decomposition of the sodium azide and the generation of nitrogen gas to fill the air bag. A vehicle, upon sensing an impact, will send an electrical charge that heats the sodium azide to high temperatures – causing the rapid formation of nitrogen gas. The solid is, however, thermally unstable and if heated above 275 °C undergoes violent decomposition. Health effects/safety hazards: Sodium azide is extremely toxic/poisonous and it can cause death. In fact, sodium azide is used in airbags for this very reason. On impact, the NaN3 (s) is ignited by an electrical spark, producing N2(g) and Na(s). (Should be 1 decimal place) physics air bags. Sodium azide is classified as a particularly hazardous substance under the OSHA Lab Standard due to its high acute toxicity, particularly by the dermal route, and is dangerously reactive when heated. Three values for the activation energy, 37.0, 59.0 and 14 kcal mol −1 have been obtained depending on the temperature range of study. C) How many grams of NaN3 are required to produce 13.0 ft^3 of nitrogen gas if the gas has a density of 1.25 g/L? Solution for Use the reaction below for the decomposition of sodium azide to sodium metal and nitrogen gas. Conclusions: Sodium azide has no explosive properties towards friction, shock or heat. Safe Handling of Sodium Azide (SAZ) Sodium azide (SAZ, CAS# 26628-22-8)1,2 is a white crystalline solid [molecular formula of (NaN 3)] used in organic synthesis and also as a well-known preservative at low concentrations in molecular biology reagents. If this is a redox reaction, show half reactions and determine if spontaneous. Sodium azide is known to be an inhibitor, by binding to the enzyme cofactor avoiding the enzymatic activitiy, of cytochrome oxidase enzyme. The results show an exothermic response of 758 J/g with the onset of exothermic decomposition being at 378°C. Sodium azide is a common preservative of samples and stock solutions in laboratories and a useful reagent in synthetic work. What is the total number of moles present in a 52.0-gram sample of NaN3 (s)? 2NaN3(s) arrow 2Na(s) + 3N2(g) a. No SOP is required if a lab has ONLY pre-made kits where sodium azide is present as a preservative at 1% concentration or less. Answer to: Automotive airbags inflate when sodium azide rapidly decomposes to its component elements. 2NAN3 (s) 2Na(s) +3N2 (g) What volume of nitrogen at… Sodium azide (NaN3) is a colorless crystalline solid and is readily soluble in water. The N2(g) inflates the airbag. The chemical equation is 2NaN3(s) -> 2Na(s)+3N2(g) right?
