Nitrogen dioxide is produced by combustion in an automobile engine. For the following reaction, 0.377 moles of nitrogen monoxide
Contact [7]

Answer:

The amount of NO₂ that can be produced 8.533 g

Explanation:

       According to question

                                2 NO(g) + O₂(g) → 2 NO₂(g)

Given

Moles of nitrogen monoxide = 0.377

Moles of oxygen = 0.278

'For NO'=\frac{Mole}{Stoichiometry}=\frac{0.377}{2} =0.1855\\'For O_{2} '=\frac{0.278}{1}= 0.278\\

Since 'NO' is the limiting reagent according to this ratio.

According to equation

         2 moles NO reacts to form 2 moles NO₂

So,  0.1855 moles NO give  = 0.1855 moles of NO₂

            Mass of 1 mole NO₂ = 46 g/mole

            Mass of 0.1855 moles = 46 x 0.1855 = 8.533 g

Step-by-step explanation:

Matter is either a <em>pure substance</em> or a <em>mixture. </em>

Pure substances

  • Are composed of one type of atom or molecule.
  • Have a constant chemical composition
  • Have fixed chemical properties
  • Have fixed physical properties

              • For example, melting point, boiling point, density, solubility

Mixtures:

  • Consist of two or more substances not chemically combined
  • Have a variable composition
  • Can be separated into two or more components by physical means

             • For example, filtration, distillation, centrifugation

  • Each component retains its own properties
