To make NaN₃ (sodium azide), sodium metal is reacted with azide ions, typically derived from ammonium azide. This reaction is performed in a controlled environment due to the compound's sensitivity and potential explosiveness. The resulting product is a white crystalline solid that can be purified through recrystallization. Proper safety precautions must be taken, as sodium azide is highly toxic and can be hazardous.
That's a wrong question. Cosmetologists do not 'make', they 'make-up'.

The empirical formula for sodium azide is NaN3.
NaN3
To calculate the total number of moles in the 52.0 gram sample of NaN3, divide the given mass by the molar mass of NaN3. First, determine the molar mass of NaN3 by summing the atomic masses of its elements (sodium, nitrogen, and three times the atomic mass of nitrogen). Then, divide the mass of the sample by the molar mass of NaN3 to find the number of moles.
NaN3 decomposed to form nitrogen gas (N2) and sodium. 2NaN3 --> 2Na + 3N2
To find the grams of sodium azide (NaN3) required to produce 5.00 grams of nitrogen (N2), we first calculate the moles of N2 produced. The molar mass of N2 is approximately 28.02 g/mol, so 5.00 grams of N2 is about 0.1786 moles (5.00 g / 28.02 g/mol). According to the reaction, 2 moles of NaN3 produce 3 moles of N2. Therefore, 0.1786 moles of N2 corresponds to 0.1191 moles of NaN3 (0.1786 moles N2 * 2/3). Finally, using the molar mass of NaN3 (approximately 65.01 g/mol), we find that 0.1191 moles of NaN3 is about 7.75 grams (0.1191 moles * 65.01 g/mol). Thus, approximately 7.75 grams of NaN3 are required.
Callod sodium acid ( NaN3 )
NaN3 (sodium azide) is an ionic compound. It is composed of sodium cations (Na+) and azide anions (N3-) which are held together by ionic bonds due to the transfer of electrons from sodium to azide.
The compound NaN3 is called sodium azide. It is commonly used as a propellant in airbags and as a reagent in organic synthesis. Sodium azide is highly toxic and should be handled with caution.
Using the balanced chemical equation for the decomposition of sodium azide, 2NaN3 -> 2Na + 3N2, we can see that 2 moles of Na3N produce 3 moles of N2. Therefore, for 2.88 mol of NaN3, we would produce 2.88 mol * (3 mol N2 / 2 mol NaN3) = 4.32 moles of N2.

The chemical equation is:2 NaN3 = 2 Na + 3N2
NaN3 (sodium azide) decomposes into Na (sodium) and N2 (nitrogen gas). The chemical equation is: 2 NaN3(s) → 2 Na(s) + 3 N2(g)
