Step-by-step explanation:
Hello there!
In this case, given the chemical reaction:
![2NaN_3\rightarrow 2Na+3N2](https://img.qammunity.org/2022/formulas/chemistry/college/ea3p0r8ie5y7mq9jzizyeum3ylar1ig63k.png)
It is possible to evidence the 2:2 mole ratio of the reactant to Na and the 2:3 mole ratio of the reactant to the N2; therefore, the following setups allows us to compute the moles of products:
![6molNaN_3*(2molNa)/(2molNaN_3)=6molNa\\\\6molNaN_3*(3molN_2)/(2molNaN_3)=9molN_2](https://img.qammunity.org/2022/formulas/chemistry/college/6illze7gosur8prj5h1nv0epmnvt81hjrw.png)
Best regards!
