<u>Answer:</u> The amount of nitrogen gas produced is 3.864 grams

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}     .....(1)

Given mass of NaN_3 = 6.00 g

Molar mass of NaN_3 = 65 g/mol

Putting values in equation 1, we get:

\text{Moles of }NaN_3=\frac{6.00g}{65g/mol}=0.092mol

For the given chemical reaction:

2NaN_3(s)\rightarrow 2Na(s)+3N_2(g)

By Stoichiometry of the reaction:

2 moles of NaN_3 produces 3 moles of nitrogen gas

So, 0.092 moles of NaN_3 will produce = \frac{3}{2}\times 0.092=0.138mol of nitrogen gas

Now, calculating the mass of nitrogen gas by using equation 1, we get:

Molar mass of nitrogen gas = 28 g/mol

Moles of nitrogen gas = 0.138 moles

Putting values in equation 1, we get:

0.138mol=\frac{\text{Mass of nitrogen gas}}{28g/mol}\\\\\text{Mass of nitrogen gas}=(0.138mol\times 28g/mol)=3.864g

Hence, the amount of nitrogen gas produced is 3.864 grams

Which is the anode (oxidation) and cathode (reduction)?
arsen [322]

Answer:

2H+ + 2e - ---> H2(g) is the cathode

2Cl - ---> Cl2(g) + 2e - is the anode

Explanation:

Hydrogen ion has gained two electrons, making it undergo reduction. While chlorine has lose two electrons, hence undergoing oxidation.
