Answer:
1.67 moles of N2 produce 2.5moles of NaN3
Explanation:
Equation of reaction:
2Na + 3N₂ → 2NaN₃
From the equation of reaction, 3 moles of N₂ produces 2 moles of NaN₃
How much is gotten from 2.5moles of 2NaN₃?
2 moles of N₂ = 3 moles of NaN₃
X moles of N₂ = 2.5 moles of NaN₃
X = (2.5 × 2) / 3
X = 1.67moles of N₂
1.67 moles of N₂ produces 2.5moles of NaN₃
The moles of HCl to neutralize the sodium hydroxide produced is<u> 0.0135 mole. </u>
Neutralization or neutralization is a chemical response wherein an acid and a base react quantitatively with each other. In a reaction in water, neutralization outcomes in there being no excess of hydrogen or hydroxide ions gift in the answer.
<u>calculation:-</u>
<u />
2Na + 2H₂O -----> 2NaOH + H₂
2 mol or 46g of Na produces 80 grams of NaOH
∴ 0.31 g of Na will produce = 80/46 × 0.31
= 0.54 gram of NaOH.
mol of NaOH = 0.54/40
= 0.0135
Since both Hcl and NaOH have the same valance factor,
1 mole NaOH is needed to neutralize 1 mol HCl
∴ 0.0135 mole of NaOH will need = 0.0135 mole of HCl
mass = 0.0135 × 36.5
=<u> 0.493 grams of HCL.</u>
