Lesson Worksheet: Properties of Nitrogen Chemistry

In this worksheet, we will practice describing and explaining the properties and reactions of the element nitrogen.

Q1:

Some of nitrogen’s physical properties and uses relate to the fact that nitrogen is inert and does not react easily. Why is nitrogen inert?

  • ANitrogen atoms have a very high first ionization energy.
  • BNitrogen atoms are very electronegative and do not easily lose electrons.
  • CNitrogen’s three p orbitals, p, p, and p, in the valence shell are only half-filled, which provides extra stability.
  • DThe diatomic molecules are held together by a very strong triple covalent bond.
  • ENitrogen’s valence electrons are not shielded from the nucleus by a full 3d orbital.

Q2:

The inert nature of nitrogen gas (N2) can be overcome by using powerful electric arcs to break the bonds between the two atoms. In an atmosphere of hydrogen and nitrogen, an electric arc causes ammonia gas (NH3) to be formed. What is the major product when an electric arc initiates a reaction in an atmosphere of nitrogen and excess oxygen?

  • ANO25
  • BNO
  • CNO23
  • DNO2
  • ENO2

Q3:

Magnesium nitride reacts vigorously with water to form ammonia and magnesium hydroxide, according to the following reaction:

MgN+HONH+Mg(OH)32232

Which of the following numbers, in the right order, are the stoichiometric coefficients missing from the reaction equation?

  • A1, 3, 1, 2
  • B1, 3, 2, 2
  • C2, 6, 4, 3
  • D2, 3, 4, 3
  • E1, 6, 2, 3

Q4:

In the preparation process of nitrogen from atmospheric air, what is the role of red-hot copper turnings?

  • ATo remove water vapor
  • BTo remove dust
  • CTo remove argon
  • DTo remove carbon dioxide
  • ETo remove oxygen gas

Q5:

Which of the following chemicals can be used to prepare nitrogen gas?

  • AAmmonium chloride and sodium nitrite
  • BAmmonium hydroxide and sodium metal
  • CAmmonium hydroxide and water
  • DAmmonium nitrite and water
  • EAmmonium nitrite and sodium chloride

Q6:

What solution can be used to remove carbon dioxide from atmospheric air when preparing nitrogen gas?

  • ASulfuric acid solution
  • BCarbonic acid solution
  • CSodium hydroxide solution
  • DCopper(II) sulfate solution
  • EHydrochloric acid solution

Q7:

Fill in the blank: During the preparation of nitrogen gas from atmospheric air in a laboratory, nitrogen is collected over to keep the nitrogen dry.

  • Awater
  • Bsodium hydroxide
  • Csodium carbonate
  • Dcopper
  • Emercury

Q8:

Which of the following is not a property of nitrogen gas?

  • AIts structure is two nitrogen atoms joined by a triple covalent bond.
  • BIt is a colorless, odorless, tasteless gas.
  • CIt has a neutral effect on litmus paper.
  • DIt is heavier than air.
  • EIt is slightly soluble in water.

Q9:

Which of the following could be used to absorb water vapor from the atmospheric air during the preparation of nitrogen gas?

  • AMercury
  • BSodium hydroxide solution
  • CCopper oxide
  • DRed-hot copper turnings
  • EConcentrated sulfuric acid

Q10:

One experimental method for isolating nitrogen from atmospheric air is to use a series of steps, each with a different purpose.

What is the purpose of bubbling air through a solution of sodium hydroxide (A)?

  • ATo remove CO2 from the air mixture
  • BTo remove water vapor from the air mixture
  • CTo remove oxygen (O2) from the air mixture

What is the purpose of bubbling the air through a concentrated solution of sulfuric acid (B)?

  • ATo remove oxygen (O2) from the air mixture
  • BTo remove water vapor from the air mixture
  • CTo remove CO2 from the air mixture

What is the purpose of passing air over strongly heated powdered copper (C)?

  • ATo remove water vapor from the air mixture
  • BTo remove oxygen (O2) from the air mixture
  • CTo remove CO2 from the air mixture
