4. Automotive airbags inflate when sodium azide, NaN 3, rapidly decomposes to its constituent elements according to the chemical equation, 2 NaN3 → 2 Na + 3 N2. 2 Na + 3 N2. How many moles of nitrogen are produced when 10000. milligrams of sodium azide decomposes? 0.07691142 mone a. 3.0000 moles 357 2 b. 0.15385 moles c. 0.23077 moles d. 230.77 moles​

B or 0.1538

Explanation:

Remark

For every mol of NaN3 that decomposes, 3 mols of N2 are produced.

10000 mg = 10 grams

NaN3 = 23 + 3*14

NaN3 = 23 + 42

NaN3 = 65

So set up the following proportion

10 grams / 65 = x /1      Cross multiply

10 * 1 = 65 x                  Divide by 65

x = 10 / 65

x = 0.1538 moles   which is B I think

yes

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
