With chem when sodium azide is activated in an automobile airbag, nitrogen gas and sodium are produced according to the equation: 2nan3(s)—> 2n3(s)+3n2(g) if 0.41 mol of nan3 reacts, what mass of nitrogen would result?

-

17.22 grams

Explanation:-

The balanced chemical equation is

2NaN3(s)—>2Na(s)+3N2(g)

According to the equation

2 mol of NaN3 gives 3 mol of Nitrogen N2

∴ 0.41 mol of NaN3 gives ( 3 mol x 0.41 mol)/ (2 mol)

= 0.615 mol

Molar mass of N2 = 14 x 2 = 28 gram / mol

Mass of nitrogen = 0.615 mol x 28 gram / mol

= 17.22 grams

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
