Why do vehicle engines produce nitrogen oxides​

Chemistry
2 answers:
Monica [59]2 years ago

Answer:

When fuels are burned in vehicle engines, high temperatures are reached. At these high temperatures, nitrogen and oxygen from the air combine to produce nitrogen monoxide. When this nitrogen monoxide is released from vehicle exhaust systems, it combines with oxygen in the air to form nitrogen dioxide.

Explanation:

Nitrogen and oxygen from the air combine at high temperatures in the engine to produce nitrogen (II) oxide by the reaction :

N2(g) + O2(g) → 2NO(g).

Nitric oxides rise in the atmosphere and are oxidized to nitrogen dioxide, NO2 which dissolves in the precipitating water to form acid rain.

The concentration of a certain sodium hydroxide solution was determined by using the solution to titrate a sample of potassium h
Ganezh [65]

Answer:

[ NaOH ] = 0.026 M

Explanation:

  • molarity NaOH = mol NaOH / Vsln(L)

∴ Vsln = 20.46 mL = 0.02046 L

  • NaOH(aq) + KHC8H4O4(aq) →  KNaC8H4O4(aq) + H2O(l)

∴ Mw KH(KHC8H4O4) = 204.24 g/mol

⇒ mol KHP = 0.1082 g / 204.24 g/mol = 5.298 E-4 mol

⇒ mol NaOH = (5.298 E-4 mol KHP)( mol NaOH/mol KHP)

⇒ mol NaOH = 5.298 E-4 mol

⇒ [ NaOH ] = 5.298 E-4 mol / 0.02046 L

⇒ [ NaOH ] = 0.026 mol/L = 0.026 M
