Question

In the reaction 2Na3N-6Na+N, how many moles of Na are produced when 6 mol of Na3N
decompose?

Answer 1

moles of Na produced = 6 moles

Further explanation

Given

Reaction

2Na3N---> 6Na+N

6 moles of Na3N

Required

moles of Na

Solution

I don't really understand the reaction in the problem, all I know is the decomposition reaction of sodium azide NaN3

2NaN₃ → 2Na + 3N₂

The reaction coefficient shows the mole ratio of the compounds involved in the reaction

From the equation(balanced), mol ratio of Na : NaN₃ = 2 : 2, so mol Na :

= 2/2 x moles NaN₃

= 2/2 x 6 moles

= 6 moles
