Based on the equation below, how many grams of nitrogen gas will be produced from the decomposition of one mole of sodium aside? Use a molar mass of 28.0 grams for nitrogen gas.

Mass of Nitrogen= 42 grams

Given

one mole of Sodium azide

Required

mass of Nitrogen

Solution

Reaction

The decomposition of one mol of sodium azide :

2 N a N 3 ( s ) → 2Na ( s ) + 3 N2 ( g )

From the equation, the mol ratio of N a N 3 ( s ) :  N2 ( g ) = 2 : 3, so mol N2 :

= 3/2 x mol N a N 3

= 3/2 x 1

= 1.5 moles

Mass of Nitrogen

= mol x molar mass

= 1.5 x 28 g/mol

= 42 grams

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
